•

Label printing is possible. (Die-cut label paper)

Die-cut label paper: Label paper that has a predefined size of labels with an interval between labels.

•

Continuous label printing is possible.

Continuous label paper: Label roll paper without labels die-cut in predefined sizes and label length is variable with an autocutter.

•

Receipt printing is possible (thickness: 145

µ m).

•

High-speed printing is possible.

Normal printing: 120 mm/s {4.72"/s} maximum

High-speed printing: 150 mm/s {5.91"/s} maximum

•

Using two-color thermal paper, two-color printing is possible (print speed: 90 mm/s {3.54"/s} maximum).

<Printer handling>

•

The printer can be placed vertically (standard) or horizontally on a table, and hung vertically on a wall.

•

Easy drop-in paper loading.

•

Cable connectors are housed in the bottom of the printer.

<Software>

•

Command protocol is based on the ESC/POS

(dpi: dots per 25.4 mm {1"})

Unidirectional forward with friction feed

(When feeding to the print starting position, paper may be fed in a reverse direction.)

80 mm {3.15"} (default setting) or variable other than 80 mm with the paper roll spacer packed in the box.

(Refer to Section 1.5, Paper Roll Supply Device, for details.)

72 mm {2.83"}, 576 dot positions

(when the paper width is 80 mm)

6) Number of characters per line:

48 (using font A when the paper width is 80 mm)

(The default setting is font A)

7) Print speed: <Normal printing> (default setting)

120 mm/s {4.72"} maximum

<High-speed printing> (selected with the memory switch)


(The high-speed printing is selected when the specified paper is used.

Refer to Section 1.6, Paper Specifications, for details.)

<Ladder bar code, two-dimensional code printing>



NOTES:

•

The print speeds listed above are values when the print density is set to the default setting at 24 V and 25

°

C {77

°

F}. The print speed may change automatically depending on the power supply voltage and the condition of the head temperature.

•

Printing speed may be slower depending on the data transmission speed and the combination of control commands.

•

Low transmission speed may cause intermittent printing. It is recommended to transmit data to the printer as quickly as possible. (Example: at least 19,200 bps for printing with font A) (bps: bits per second)

•

When the ladder bar code or 2-dimensional code is printed, the print starts when the specific paper feed speed is reached. Therefore, the paper may be fed for the maximum 10 dot lines, depending on the paper feed speed at the time that the print data is received.

8) Line spacing: 3.75 mm {0.15"}

(Programmable by control command.)

1.3 Autocutter

1) Cutting method: By separated-blade scissor

2) Cutting type: Full cut (cuts paper completely) (default setting)

Partial cut (one point left uncut) is also available as a dealer option.

(Set by changing the position of the autocutter unit.)

NOTES:

•

Install the paper exit guide packed in the box with the printer when the autocutter is used with a full cut, positioning the printer horizontally. If the printer is installed horizontally without the paper exit guide, and the autocutter full cut is used, a cut sheet may drop in the paper path, and it may cause a double-cut, paper jam, or autocutter error. However, if the printer is installed vertically or if the autocutter is used with a partial cut, the paper exit guide does not have to be used.

•

After cutting, paper must be fed approximately 1 mm {16/406"} or more, then be stopped, because if it is not, paper may be jammed in the autocutter unit.

•

To prevent dot displacement after cutting, it is recommended to feed paper for approximately 1 mm {16/406"} or more before printing.

•

Changing partial cut or full cut is not controlled by a software command.

•

If a die-cut label is used, cut the backing paper (liner) between labels (face stock).

Do not cut the label paper (face stock), because the label adhesive bonds to the autocutter blade, causing a cutting problem.

•

If the adhesive agent on the labels sticks to the autocutter when the continuous label paper is used, it may dull the blade. In this case, clean the blade. (Refer to section 1.12 and APPENDIX E)

3) Possible thickness to be cut with a manual cutter:

100 m or less.

NOTES:

•

The manual cutter installed in the autocutter unit is intended to cut the receipt (paper thickness: approximately 75

µ m) manually.

•

If a paper thickness of 100

µ m or more is cut with the manual cutter, be sure to cut paper so that the paper is not out of alignment.

•

The cutting type (partial cut or full cut) must be selected before the printer is first used. If the cutting type is changed from partial cut to full cut after the printer has been used, the printer may not be reliable because the wear-out level of the cutter blade differs.

1.4 Function of the Paper Detectors

The printer has the paper detection functions described below, depending on the type of paper to be used and the memory switch settings:

1) Paper end detection

This detects the presence of the paper, regardless of the type of paper or the memory switch settings.

2) Label position detection

This detects the label position if the origin of the layout is set to “label” with the memory switch or if the auto-setting mode of the paper layout specifies “label.”

3) Black mark detection

This detects the black mark position if the origin of the layout is set to “black mark” with the memory switch or if the auto-setting mode of the paper layout specifies “black mark paper” (Refer to 3.8, Auto-setting Mode for Paper Layout, for details.)

Outside: 31.4 mm {1.24"} c) Near-end adjustment: Adjusting screw

Fixed position #1 (approximately 36 mm {1.42"})

#2 (approximately 41 mm {1.61"})

(The adjusting screw has two positions.)

NOTES:

•

A command can be used to select whether printing is stopped or not when the paper near end is detected.

•

When the paper roll diameter becomes sufficiently small, the sensor detects a near-end of the paper roll, and the PAPER OUT LED indicator lights. If the sensor is enabled by ESC c 4, the printer stops printing.

After installing a new paper roll, close the roll paper cover; then the printer restarts printing.

3) Paper width selection: 80 mm {3.15"} (default setting)

By adjusting the paper roll spacer, it is also possible to set optional positions in the range of 38 to 70 mm {1.50 to 2.76"}. The range of 71 to 79 mm {2.80 to 3.11"} cannot be set.

NOTES:

•

Be sure to set the paper width with the memory switch to adjust printing to the print width.

•

Never change the paper width from narrow to wide once you set the paper width to narrow.

Example: 60 mm {2.36"}

→

80 mm {3.15"}

The reason not to change the width setting if the printer has ever been used is because once narrow paper is used, some part of the head always contacts the platen. Therefore, if a width setting of 80 mm is set, there is a possibility that the head or the cutter blade may be worn out. By this means, printing is inhibited in the area described above.

•

If roll paper other than the specified ones is used, the paper near-end may not be detected correctly. However, the paper near-end for roll paper that has a 12 mm

{0.47"} inside diameter and 18 mm {0.71"} outside diameter or 12 mm inside diameter and 22 mm {0.87"} outside diameter can be detected, even though it is not as accurate as the specified roll paper.

1.6 Paper Specifications

1) Paper type: Specified thermal paper

The following four kinds of paper can be used:

• Receipt paper, continuous label paper (without black mark)

• Receipt paper (with black mark)

• Die-cut label paper (without black mark)

• Die-cut label paper (with black mark)

Refer to Function 49 of the GS ( E command for the paper layout details.

NOTES:

•

Die-cut label paper is a label paper that has a predefined size of labels with an interval between labels.

•

Continuous label paper is a label roll paper without labels die-cut in predefined sizes and label length is variable with an autocutter.

•

Continuous label paper can be used with the same settings as for receipt paper

(without black mark).

•

When a die-cut label (with black mark) is printed, the user must consider the print position and the autocutting position. If printing is executed on the backing paper

(liner) or the label on backing paper is cut by the autocutter, the thermal print head may be damaged.

•

Die-cut labels (with black marks) cannot be used in the automatic paper layout setting mode.

Two-color printing is performed using a two-color thermal paper, if the two-color print is selected by the customized value setting with Function 5 of the GS ( E command.

•

There may be some cases where the print color may not be clear depending on the print pattern.

•

Printing with Color 2 (red on the specified two-color thermal paper) may fade over time, depending on the environmental circumstances. To keep the print for long-term storage, it is recommended to print with Color 1 (black on the specified two-color thermal paper).

•

The reliability when two-color thermal paper is used differs from the reliability when single-color thermal paper is used. Refer to Section 1.12, Reliability, for details.

•

Make sure to use the specified two-color thermal paper in two-color printing. Otherwise, the thermal print head may be damaged.

NOTES:

•

The printable area may be out of alignment by 2 mm {0.08"} maximum (left or right), due to the paper position or tolerance of parts. Therefore, the print area must be set in the range of more than 2 mm from the edges of the paper. To make the margin for both sides safely, it is recommended to set a margin of 2.6 mm {0.1"} or more, as shown in

Figure 1.7.1.

•

A roll paper which has a 71 to 79 mm of the paper width cannot be used because of the thickness of the paper roll spacer.

The signal indicates whether the printer is correctly connected and is ready to receive data. SPACE indicates that the printer is ready to receive data. The signal is always SPACE except in the following cases:

•

During the period from when the power is turned on to when the printer is ready to receive data

•

During the self-test

Input Changing memory switch Msw 1-8 enables this signal to be used as a reset signal for the printer.

The printer is reset when the signal remains SPACE for 1 ms or more.

When the receive buffer capacity is specified to 45 bytes:

When the remaining space in the receive buffer drops to 16 bytes, the printer status becomes

“buffer full” and it remains “buffer full” until the space in the receive buffer increases to 26 bytes.

•

When the receive buffer capacity is specified as 4KB:

When the remaining space in the receive buffer drops to 128 bytes, the printer status becomes

“buffer full” and it remains “buffer full” until the space in the receive buffer increases to 256 bytes.

•

In case , XON is not transmitted when the receive buffer is full.

•

In case , XOFF is not transmitted when the receive buffer is full.

•

When memory switch Msw 1-3 is set to OFF, XON is not transmitted if the printer is in offline state in case ➁ .

2.1.1.5 Notes on setting the handshake operation using memory switch Msw 1-3

1) The printer mechanism stops but does not become busy when: an error has occurred, the cover is open, printing stops due to a paper-end, or paper is fed using the paper FEED button.

2) When setting the memory switch to enable handshaking with the printer, be sure to check the printer status using the GS a command and the ASB function. In this setting, the default value of n for GS

a is 2. The printer automatically transmits the printer status, depending on online/offline changes.

3) When using DLE EOT, DLE ENQ, and DLE DC4 be sure that the receive buffer does not become full.

•

When using a host that cannot transmit data when the printer is busy:

If an error has occurred, DLE EOT, DLE ENQ, and DLE DC4 cannot be used when the printer is busy due to a receive buffer-full state.

•

When using a host that can transmit data when the printer is busy:

When the receive buffer becomes full while transmitting bit-image data, and DLE EOT, DLE

ENQ, or DLE DC4 is used while sending bit-image data, the code is processed as bit-image data. The data transmitted when the receive buffer is full may be lost.

Example: Check the printer status using GS r after transmitting each line of data and use the

4KB receive buffer. Transmit data one line at a time so that the receive buffer does not become full.

2.1.2 IEEE 1284 Bidirectional Parallel Interface (Parallel Interface Specifications)

Copyright © 1994 by the Institute of Electrical and Electronic Engineers, Inc.

2.1.2.1 Compatibility mode

1) Outline

Compatibility mode supports the compatibility with a Centronics parallel interface.

2) Specifications

Synchronization:

Handshaking:

Signal levels:

Connector:

8-bit parallel

Externally supplied nStrobe signals nAck and Busy signals

ADS-B36BLFDR176 (Honda) or equivalent (IEEE 1284 Type B)

3) Switching between online and offline

The printer is not equipped with any online/offline switch. The printer is placed into offline status in the following conditions:

1) When the power is turned on or until the printer becomes ready for data transmission after it is initialized by the reset signal (nInit) from the interface.

2) During the self-test.

3) When the cover is open.

4) During paper feeding using the paper FEED button.

5) When the printer stops printing due to a paper-end (in cases when an empty paper supply is detected by either the paper roll end detector or the paper roll near-end detector with a printing halt feature due to a paper end enabled by ESC c 4).

6) During standby status for macro execution.

7) When a temporary abnormality occurs in the power supply voltage.

8) When an error has occurred.

2.1.2.2 Reverse mode (data transmission from printer to host)

The STATUS data transmission from the printer to the host proceeds in the Nibble or Byte mode.

•

Description

This mode allows data transmission from the asynchronous printer under the control of the host.

Data transmissions in the Nibble Mode are made via the existing control lines in units of four bits

(a nibble). In the Byte Mode, data transmissions are accomplished by making the eight-bit data lines bidirectional.

Both modes cannot work at the same time as the Compatibility Mode, thereby causing half duplex transmission.

2.1.2.7 Reception of status from the printer through the bidirectional parallel interface

In the bidirectional parallel interface specifications, the printer status transmission is available by using the both-way communication facility in the Nibble/Byte Modes in accordance with the IEEE 1284.

In this case, unlike the RS-232 serial interface specifications, the real-time interruptions from the printer to the host are disabled and thus precautions must be taken:

1) The allowable capacity of the printer internal buffer is 99 bytes (except ASB status). Status signals exceeding this capacity will be discarded. To prevent possible loss of status, the host shall be ready for data reception (Reverse Mode).

2) When ASB is used, the host is preferably in the wait state for data reception (Reverse Idle Mode).

When this state is not available, the host shall enter the Reverse Mode to continually monitor the presence of data.

3) When ASB is used, preference shall be given to the ASB status for transmission over the other status signals.

3.3 Switches and Buttons

3.3.1 Power Button (Non-locking push button)

1) The power button located on the upper right front of the printer turns the power on or off. The power button is enabled or disabled with a DIP switch.

NOTE: Turn on the power only after connecting the power supply.

2) To turn the power off, press the power button for at least 3 seconds.

3) The printer operates depending on the DIP switch setting (enable/disable power button function) as shown in Table 3.3.1.

Table 3.3.1 Printer Operation by DIP SW1-1

When the power button is pressed for at least 3 seconds

When the power off is controlled by the host PC

(Transmission of DLE DC4 2)

Setting of the DIP SW 1-1

On (power button is disabled) Off (power button is enabled)

The printer power is turned off. The printer is reset

(only when an error has occurred). (*1)

The printer flashes the

POWER LED after power off processing. (*2)

The printer power is turned off.

NOTES: *1: Refer to Section 3.8.1 for types of error.

*2: Refer to Section 3.4.1 for the POWER LED flashing pattern.

<How to disable the power button>

1) Power button cover

A power button cover option is available. Use this cover to avoid turning power off accidentally.

2) DLE DC4 (Execute power-off sequence)

To control the printer’s power off in situations when the power button is covered, disable the power button using the DIP switch and the power off command DLE DC4. (Refer to

Appendix G for details.)

NOTE: Pulling the paper out forcibly causes turning the power button on when the power button is turned off, if +24 V power voltage is supplied and the DIP switch 1-1 is off

(the power button is effective).

3.3.2 Panel Buttons

1) FEED button: Non-locking push button

[Function]

•

If you push this button once and release it, the printer feeds paper one line, based on the line spacing set by ESC 2 and ESC 3. However, paper feeding using the FEED button cannot be performed under the following conditions:

① The paper roll end sensor detects a paper end.

② When the roll paper cover is open.

•

If you push this button when the printer is in the macro execution standby state, the defined macro is executed.

•

During self-test printing, you can stop the self-test temporarily by pressing this button and restart it by pressing the button again.

NOTE: This button is disabled by ESC c 5.

Hex 0A

Decimal 10

[Description]

•

In standard mode

• Prints the data in the print buffer and feeds one line based on the current line spacing.

• If the paper layout (the origin of the layout) specifies “bottom of the label” or “top of the black mark” in standard mode, the printer executes either one of the following operations when the paper feed amount exceeds the printing area in the vertical layout:

• If the maximum height of the characters in one line exceeds the printing area specified in the vertical layout, the printer feeds the paper to the print starting position on the next label and executes the process of this command from the print starting position on the next label.

• If the maximum height of the characters in one line does not exceed the printing area specified in the vertical layout, but the paper feed amount exceeds the printing area, the printer executes printing on the current label and feeds the paper to the bottom of the printing area.

•

In page mode

• Feeds one line based on the current line spacing.

•

Frequent write command executions by this command may damage the NV memory.

Therefore, it is recommended to write to the NV memory no more than 10 times a day.

[Notes]

•

The user setting mode is a special mode to change the values in the NV user memory with this command.

•

In Function 2, the printer performs a software reset. Therefore, the printer clears the receive and print buffers, and resets all settings (user-defined characters, macros, and the character style) to the mode in effect at power on.

•

The customized values can be reviewed with Function 4, 6, 12, or 50, even though the printer does not enter the user setting mode.

•

Frequent write commands by this command, may damage the NV memory. Therefore, it is recommended to write to NV memory no more than 10 times a day.

•

While processing this command, the printer is BUSY while writing data to the NV user memory and stops receiving data. Therefore it is prohibited to transmit data including the real-time commands during the execution of this command.

•

This function (fn = 49) is enabled only in the user setting mode.

•

Make enough margin to set the cutting position.

•

If the distance between the cutting position and the next print starting position is set to 3.6 mm {0.14"} or less, the printer will skip one label and feed to the top of the next label, because the printer cannot perform feeding in reverse to set the paper to the print starting position.

•

When sa = “49” is specified, die-cut label printing (with black marks) is possible. However, there is no way that the printer can differentiate the type of paper – label (with black marks) or receipt (with black marks). Therefore, the user must consider carefully the print position and the cutting position for the autocutter.

•

The autocutting position se must be set between the labels.

•

The print position – sd and sf (top and bottom margin) must be set over 2 mm {0.08"} from the top and the bottom of the label, respectively.

•

The print position – sg and sh (left and right margin) must be set over 2.8 mm {0.11"} from the left and the right of the label, respectively. e

2.8 or more sh

•

If the paper layout information is already written in the NV memory and the user wants to change to a new type of paper, the user must have the current type of paper (not the new type) loaded in the printer when this command is used to change to the settings for the new paper.

•

When two or more types of paper are used alternately, it is recommended to use the automatic paper recognition function as described in Section 3.8, not setting the paper layout.

•

The paper which has a 71 to 79 mm {2.80 to 3.11"} of the paper width cannot be used because of the thickness of the paper roll spacer.

APPENDIX A: MISCELLANEOUS NOTES

A.1 Notes on Printing and Paper Feeding

1) Because the TM-L90 series printer is a line printer, it automatically feeds paper after printing the data.

Therefore, when the line spacing for one line is set to a smaller value than the print data, paper may be fed more than the set amount just to print the data.

For example, when the line spacing for one line is set to 10 dots and only paper feeding is executed, paper is fed for 10 dots; however, if bit-image characters are printed, paper is fed for 24 dots. (Refer to Table A.1.)

When only rotated characters are printed on one line, paper feeding is executed as shown in Table A.1 and A.2.

2) When the printer goes to the standby (data-waiting) state during printing, it temporarily stops printing and feeding paper. When data is transmitted and printing is executed, paper may shift 1 to 3 dots from the print starting position, which especially affects bit-image printing.

3) Interval of autocutting operation in the receipt section

For driving the autocutter of the receipt section, the interval should be a minimum of 10 lines of printing or paper feeding (to prevent small pieces of cut paper from dropping into the autocutter).

A.2 Notes on Printer Installation

•

Connect the external power supply to the printer power supply connector. Then plug in the external power supply and turn it on if necessary. Be sure not to connect the external power supply with the wrong polarity. If it is connected incorrectly, the internal circuit fuse of the printer may be blown or the external power supply may be damaged.

•

The power supply voltage is within the range of 24 V

±

7%. If the power supply voltage drops to the outside the range above during printing, the printer stops printing and waits until the voltage returns to normal and then automatically begins printing again. Therefore, printing speed may slow, the print pitch may not be correct, and some dots in some characters may not be printed.

•

Both high and low voltage errors are shown in Table 3.9.3. The flashing patterns are shown in the table.

•

When either a high or low voltage error occurs, turn off the power as soon as possible.

A.3 Other Notes

1) Printer mechanism handling

•

Do not pull the paper out when the cover is closed. Especially when it is required that the paper is pulled out after turning the power off, the power may be turned back on.

•

Because the thermal elements of the print head and driver IC are easy to break, do not touch them with any metal objects.

•

Since the areas around the print head become very hot during and just after printing, do not touch them.

•

Do not use the cover open button except when necessary.

•

Do not touch the surface of the print head because dust and dirt can stick to the surface and damage the elements.

•

Thermal paper containing many of Na + , K + , and Cl ions can harm the print head thermal elements. Therefore, be sure to use only the specified paper.

2) Thermal paper handling

① Notes on using thermal paper

Chemicals and oil on thermal paper may cause discoloration and faded printing.

Therefore, pay attention to the following: a) Use water paste, starch paste, polyvinyl paste, or CMC paste when gluing thermal paper. b) Volatile organic solvents such as alcohol, ester, and ketone can cause discoloration. c) Some adhesive tapes may cause discoloration or faded printing. d) If thermal paper touches anything which includes phthalic acid ester plasticizer for a long time, it can reduce the image formation ability of the paper and can cause the printed image to fade. Therefore, when storing thermal paper in a card case or sample notebook, be sure to use only products made from polyethylene, polypropylene, or polyester. e) If thermal paper touches diazo copy paper immediately after copying, the printed surface may be discolored. f) Thermal paper must not be stored with the printed surfaces against each other because the printing may be transferred between the surfaces. g) If the surface of thermal paper is scratched with a hard metal object such as a nail, the paper may become discolored.

② Notes on thermal paper storage

•

Since color development begins at 70

°

C {158

°

F}, thermal paper should be protected from high temperatures, humidity, and light, both before and after printing. a) Store paper away from high temperatures and humidity.

Do not store thermal paper near a heater or in enclosed places exposed to direct sunlight. b) Avoid direct light.

Extended exposure to direct light may cause discoloration or faded printing.

•

When the printer is not used for one week or more, it is recommended not to leave the thermal paper between the platen and the print head.

3) Others

•

Because this printer uses plated steel, the cutting edges may be subject to rust.

However, this does not affect the printer performance.

APPENDIX D: PRINT HEAD CLEANING

Paper dust on the heating elements may lower the print quality. In this case, clean the print head as follows:

1) Open the roll paper cover.

2) Clean the thermal elements of the print head using a cotton swab moistened with an alcohol solvent (ethanol, methanol, IPA).

NOTES:

•

Do not touch the print head thermal elements.

•

Do not scratch the print head.

3) Insert roll paper and close the roll paper cover.

NOTE: The print head becomes very hot just after printing and is very dangerous. Be sure to allow the print head to cool down (after printing) before cleaning it. Also, be sure to turn off the printer power before cleaning the print head and turn on after the alcohol solvent is dried out completely.

Figure D.1 Print Head Thermal Elements

(*) Depending on the roll paper used, paper dust may stick to the platen roller and roll paper end sensor. To remove the paper dust, clean the platen roller and roll paper end sensor with a cotton swab moistened with water.

Also, be sure to turn on the printer power after the water is dried out completely.

APPENDIX H: NOTES ON UPDATING THE MAINTENANCE COUNTER

AND TURNING THE PRINTER’S POWER OFF

H.1 About updating the maintenance counter

•

This printer has a maintenance counter function, as described in the command description for

GS g 0 and GS g 2.

•

The values of the maintenance counter are automatically stored in the NV memory every 2 minutes (or 4 minutes maximum) when the printer is operating, except in the power save mode.

•

However, if the power off is performed as described in Section H.2, the printer stores the latest values of the maintenance counter and executes the power off control, regardless of the updating interval described above.

•

If the printer is not sending/receiving data or is not operating for two seconds while the power is turned on, the printer enters the power-saving mode and all of the values of the maintenance counter including the printer operation time stop counting.

H.2 About the printer’s power off

In order to store the latest values of the maintenance counter, the print head must be capped before the printer is turned off. This is done when the power switch (front) is turned off.

If the power switch is covered by the attached power switch cover, make sure to execute the DLE

DC4 (n = 2) command first from the host computer to the printer. Below is the description of how to turn the power off using the power switch.

H.2.1 Printer setup by the host with printer power off

Follow the procedure below for setting up the printer first.

1) Turn the printer's power off using the power button in the front.

2) Wait until the POWER LED turns off.

3) Turn DIP switch 1-1 on.

4) Turn the printer's power on using the power button.

5) Attach the power button cover on the power button.

H.2.2 Power off procedure by the host

The following is an example of the printer power off process when the printer is turned off using the

DLE DC4 (fn = 2) command.

1) The host transmits the following continuous procedure before the system is turned off:

➀ Executes the last print command such as LF, ESC d, etc.

➁ Executes GS ( D p L p H m a b (p L =3, p H =0, m =20, a =2, b =1)

➂ Executes GS r n (n =1)

2) The host waits for the paper sensor status sent from the printer in response to the GS r n command.

3) The host transmits DLE DC4 fn a b (fn =2, a =1, b =8).

4) The host waits for the power off status.

•

The values of the maintenance counter are stored and the power-off sequence is performed within 10 seconds after the host transmits DLE DC4 fn a b; then the power off status is transmitted.

•

If the power off status is not checked, the host waits for 10 seconds or more after transmitting DLE DC4 fn a b.

•

For the serial interface model, the printer status is transmitted regardless of the condition of the host.

•

For the parallel interface model, after the host transmits DLE DC4 fn a b, the printer is required to be ready for receiving data from the host.

NOTE: The printer executes the software sequence, but the power is not cut.

5) Please turn the host power off.

NOTE: Do not execute a reset to the printer until the printer power is turned off after transmitting DLE DC4 (fn = 2).

APPENDIX I: NOTES ON PRINTING 2-DIMENSIONAL CODES

The TM-L90 supports 2-dimensional code printing.

Be sure to follow the notes below when printing 2-dimensional codes.

1) When printing PDF417 (2-dimensional code), it is recommended to set the height of one module of the symbol to three to five times the width of one module, also making sure that the total height is almost 5 mm {0.20"} or more.

2) The recognition rate of the 2-dimensional code may be affected by such items as different widths of the modules, print density, environmental temperature, type of the thermal paper, and characteristics of the reader. Therefore, the user should check the recognition rate in advance so that the limitations of the reader can be considered.

APPENDIX K: NOTES ON SETTING MEMORY SWITCH 8-6

“FEEDING PAPER TO THE PRINT STARTING

POSITION AT POWER ON IS DISABLED”

This printer can set a paper feeding to the print starting position at power on or software resetting disabled with memory switch 8-6.

Note the following points if this setting is used.

•

This setting is enabled only when the paper layout is set. The paper layout can be set with

<Function 49> of GS ( E, GS ( A, or a panel operation (refer to section 3.8).

•

This setting performs on the assumption that the paper is already fed to the print starting position at power on or software reset. If the paper has not been set to the print starting position, the print position of the first print may be misaligned or the paper layout error

(recoverable error) may occur. Therefore, take in consideration the following points: a) Turing the power off or resetting the printer must be performed in the condition that the paper is fed to the print starting position. Please note that the software reset is activated in the following conditions:

• When Function 2 of GS ( E is executed by changing the memory switch.

• With the parallel interface model, when the host PC reboots.

• When a reset signal is sent from the host PC. b) Do not open the cover or exchange the paper while the power is off.

1 If the cover is opened or the paper is exchanged while the power is off, open and close the cover once while the power is on.

2 If printing is performed without the operation described above, the paper layout error

(recoverable error) may occur. Execute the DLE ENQ (n = 2) command to recover from the error and feed the paper to the print starting position if this error occurs.
