3 Sw itching between on -line and off-line

The printer does not have an on-line/off-line switch.

The printer goes off-line:

• Between when the power is turned on (including reset using the interface) and when the printer is ready to receive data.

• During the self-test.

• When the cover is open.

• D uring paper feeding using the paper feed button.

• When the printer stops printing due to a paper-end (in cases when an empty pape r supply is detected by either paper roll end detector or the paper roll near-end detector with a printing halt feature by

ESC c4).

• During macro executing stand by status.

• When a temporary abnormality occurs in the power supply voltage.

• When an error has occurred.

·This com c ls all NV bit image tha t have already been defined by this command. The printer can not redefine only one of several data definitions previously defined. In this case, all data needs to be sent again.

·From the beginning of the processing of this command till the finish of hardware reset, mechanical operations (including initializing the position of the printer head when the cover is open, paper feeding by using the

FEED button, etc.) cannot be performed.

· During processing this command, the printer is in BUSY when writing the data to the NV user memory and stops receiving data. Therefore it is

TITLE : WTP-150

Page -58 -

prohibited to transmit the data including the real-time commands during the execution of this command.

· NV bit image means a bit image which is defined in a non-volatile me mory by FS q and printed by FS p.

·In standard mode, this command i s effe ctive only when processed at the beginning of the line.

·In page mode, this command is not effective.

· This command is effective when 7 bytes <FS-yH> is processed as a normal value.

·When the amount of the data exceeds the capacity left in the range defined by xL, xH, yL, yH, the printer processes xL, xH, yL, yH out of the defined range.

·In the first group of NV bit image, when any of the parameters xL, xH, yL, yH, is out of the definition range, the command is disabled.

·In groups of NV bit image other than the first one, when the printer processes xL, xH yL, yH out of the defined range, it stops processing th is command and stars writing into the NV images. At this time, NV bit image that haven’ t been defined are disabled (undefined), but any NV bit images before that are enabled.

·The d indicates the definition data. In data (d) a 1 bit specifies a dot to be printed and a 0 bit specifies a dot not to be printed.

·This command defines n as the number of a NV image. Number rise in order from NV bit imag e 01H. Therefore, the first data group [xL xH yL yH d1...dk] is NV bi t image 01H, and the last data group [xL xH yL yH grees with the number of NV bit images spe cified by command FS p.

·A definition data of a NV bit image consists of [xL xH vL vH d1...dk].

Therefore, when only one NV bit image is defined n=1, the printer processe s a data group [xL xH yL yH d1...dk] once. The printer uses

([data:( xL + xH

×256) × (yL + yH × 256) × 8] + [header:4]) bytes of NV memory.

·The definition area in this printer is a maximum of 2M bits (256K bytes).

This command can define several NV bit image, but cannot define a bit

[Notes] image data whose total capacity [bit image data + header] exceeds 2M bytes (256K bytes).

·The printer is busy immediately before writing into NV memory, regardless of the setting of DIP switch 2-1.

· The printer does not transmit ASB status and perform sta tus detection during processing of the command even when ASB is s pecified.

· When this command is received during macro definition, the prin ter ends macro definition, and begins performing this command.

· Once a NV bit image is defined, it not erased by performing ESC @, reset, and power off.

· This command performs only definition of a NV bit im age and does not perform printing. Printing of the NV bit im age is performed by the FS q command.

·F requent write command execution may cause damage the NV memory.

Therefore, it is recommended to write the NV memory 10 times or less a day.

· Th e printer performs a hardware reset after the procedure to place the image into the NV memory. Therefore, user-defined characters, downloaded bit image, and macros should be defined only after completing this command. The printer clears the receive and print buffers and resets the mode to the mode that was in effect at power on. At this time, DIP switch setting are checked again. n is the number of the NV bit

The printer automatically transmits the status whenever the enabled status item changes. The disabled status items may change, in this case, because each status transmission represents the current status.

·If all status items are disabled, the ASB function is also disabled.

·If the ASB is enabled as a default, the printer transmits the status when the printer data reception and transmission is possible at the first time from when the printer is turned on.

·The following four status bytes are transmitted without confirming whether the host is ready to receive data. The four status bytes must be consecutive, except for the XOFF code.

·Since this command is executed after the data is processed in the receive buffer, there may be a time lag between data reception and status transmission.

·When the printer is disabled by ESC = (Select peripheral device), the four status bytes are transmitted whenever the status changes.

·When the bar code system used is UPC-A or UPC-E, the printer prints the bar code data after receiving 12 bytes bar code data and processes the following data as normal data.

·When the bar code system used is JAN 13, the printer prints the bar code after receiving 13 bytes bar code data and processes the following date as normal data.

·When the bar code system used is JAN 8, the printer prints the bar code after receiving 8 bytes bar code data and processes the following data as normal data.

·The number of data for ITF bar code must be even numbers. When an odd number of data is input, the printer ignores the last received data.

[Details for②] · n indicates the number of bar code data, and the printer processes n bytes from the next character data as bar code data.

·If n is outside of the specified range the printer stops command processing and processes the following data as normal data.

[Details in standard made]

·If d is outside of the specified range, the printer only feeds paper and process the following data as normal data.

·If the horizontal size exceeds printing area, the printer only feeds the paper.

·This command feeds as much paper as is required to print the bar code, regardless of the line spacing specified by ESC 2 or ESC 3.

·This command is enabled only when on data exists in the print buffer.

When data exists in the print butter, the printer processes the data following m as normal data.

·After printing bar code, this command sets the print position to the beginning of the line.

·This command is not affected by print modes (emphasized, doublestrike, underline, character size, white/black reverse printing, or 90˚ rotated character, etc), except for upside-down printing mode.

[Details in page made]

·This command develops bar coed data in the print buffer, but does not print it. After processing bar cod data, this command moves the print position to the right side dot of the bar code.

·If d is out of the specified rang, the printer stops command processing and processes the following data as normal data. In this case, the data butter position does not change.

·If bar code width exceeds the printing area, the printer does not print the bar code but moves the data buffer position to the left side out of the printing area.

·Refer to Figure 3.12.3 for bar code data buffer position.

When CODE 128 (m = 73) is used:

·Refer to Appendix J for the information of the CODE 128 bar code and is code table.

·When using the CODE 128 in this printer, take the following points into account for data transmission:

① The top of the bar code data string must be code set selection character (any of CODE A, CODE B or CODE C) which selects the first code set.

② Special characters are defined by combining two characters

·If the top of the bar code data is not the code set selection character, the printer stops command processing and processes the following data as normal data.

·If combination of “ {“ and the following character does not apply any special character, the printer stops command processing and processes the following data as normal data.

·If the printer receives characters that cannot be used in the special code set, the printer stops command processing and processes the following data as normal data.

·The printer does not print HRI characters that correspond to the shift characters or code set selection characters.

·HRI character for the function character is space.

<Others>

·HRI characters for the control character (<00>H to <1F>H and <7F>H)are space.

Be sure to keep spaces on both right and left sides of a bar code.

(Spaces are different depending on the types of the bar code.)

[Details] ·When using a serial interface

·When DTR/DSR control is selected, the printer transmits only 1 byte after confirming the host is ready to receive data (DSR signal is SPACE). If the host computer is not ready to receive data (DSR signal is MARK), the printer waits until the host is ready.

When XON/XOFF control is selected, the printer transmits only 1 byte without confirming the condition of the DSR signal.

·This command is executed when the data in the receive buffer is developed. Therefore, there may be a time lag between receiving this command and transmitting the status, depending on the receive buffer status.

·When Auto Status Back (ASB) is enabled using GS a, the status transmitted by GS r and the ASB status must be differentiated using the table in Appendix G.

·The status types to be transmitted are shown below:

[Details] ·In standard mode, this command is effective only when there is no data in the print buffer.

·This command has no effect in all print modes (character size, emphasized, double-strike, upside-down, underline, white/black reverse printing, etc.) for raster bit image.

·If the printing area width set by GS L and GS W is less than the minimum width, the printing area is extended to the minimum width only on the line in question. The minimum width means 1 dot in normal (m=0,48) and double-height (m=2,50), 2dots in double-width (m=1,49) and quadruple

·Data outside the printing area is ready in and discarded on a dot-by-dot basis.

·The position at which subsequent characters are to be printed for raster bit image is specified by HT(Horizontal Tab) ESC $ (Set absolute print position), ESC ＼ (Set relative print position), and GS L (Ste left margin).

If the position at which subsequent characters are to be printed is not a multiple of 8, print speed may decline.

·The ESC a (Select justification) setting is also effective on raster bit image.

·When this command is received during macro definition, the printer ends macro definition, and begins performing this command. The definition of the command should be cleared.

·d indicates the bit-image data. Set time a bit to 1 prints a dot and setting it to 0 does not print a dot.
