Installation

Follow the precautions listed below when setting up your printer. They are designed to help you keep your printer working at its best.

- Plug your power supply into an appropriate grounded outlet.

- Place your printer on a flat hard surface, like a tabletop.

- Keep your printer out of direct sunlight.

Installing the P aper

1. Remove the printer cover by pressing on the groove patterns to pop the front edge up. Lift off the cover.

2. Press the rocker switch to the left. The light will go off.

3. Unroll several inches of the paper.

11111

4. Cut a straight edge on the paper roll if it is jagged.

This will facilitate the entry of the paper into the printer.

5. Slide the paper through the slot connecting the paper compartment and the printer compartment. You can slide it in about one-quarter inch before it stops.

6. While holding the paper in place, press the rocker switch to the Paper Feed position. The printer will activate, and a rubber roller will pull the paper into the printer compartment. Hold the switch in the Paper

Feed position until the paper emerges from the top of the printer mechanism.

7. When an inch of paper has emerged from the top of the printer, release the Paper Feed button.

8. Now pull the paper through the printer, until several inches are exposed.

9. Slide the paper through the slot in the printer cover.

22222

33333

10. Push the back of the printer cover down and into place.

11. Press the front of the printer cover down to lock in place.

12. Put the paper spindle into the paper roll as shown below, and place the roll with the spindle onto the snaps near the back of the printer. Turn the paper roll to take up any slack in the paper feeding to the printer. Make sure the roll of paper turns freely. If it does not turn freely, the paper will jam and will possibly damage the printer mechanism.

o Remove the P aper

Roll

1.

Advance the paper about one inch beyond the paper cutter by using the Paper Feed switch.

2. Lift the paper roll away from the printer housing and cut the paper feeding to the printer with scissors. Try to make the cut as square as possible to help the next time you reload the paper.

3. Pull the remaining paper through the printer mechanism. Be sure to pull the paper from the top

(paper cutter side).

W ARNING! Pulling the paper out of the back of the printer will damage the print mechanism.

Operation

Connecting and

PPPPPowering Up our P rinter

1. Attach the appropriate cable between the printer and your host device. The connector on the printer side is

“keyed” so that you cannot plug the cable in the wrong way. This means that the pins should be positioned so that a slight pressure will seat the cable properly. Do not force the pins in. Doing so could damage the cable.

For DC modified units supplied with cable, connect positive voltage to striped wire.

2. Plug the power cord into the back of the printer. Plug the transformer into an appropriate AC outlet. The unit will power up automatically and print R means the printer is ready to print.

R eady

The Paper Feed switch on the printer is a rocker type switch. Push the left side of the rocker switch to toggle the printer on and offline. Push the right side of the switch to advance the paper.

Your printer is now ready for printing.

The printer stores characters for printing until one of two things happens:

1. Its line buffer is filled.

2. It receives a line feed (hexadecimal 0A) or a carriage return (hexadecimal 0D) code.

When (1) or (2) occurs, the printer prints out the contents of its line buffer. If the buffer is empty when the carriage return is received, the printer simply advances the paper one line, leaving a blank line in the printout.

Maintenance

When printing becomes faint or difficult to see, replace the ribbon in your printer with an NCI cartridge ribbon.

Changing the P rinter

Ribbon

If your printer is used infrequently, the print impression may become weak because the ribbon has dried out. To advance the ribbon to a new section, hold down the

Paper Feed switch for several seconds.

Below are the steps for replacing the ribbon:

1. Turn the printer offline.

2. Four small grooves are embossed on each side of the printer cover. Push down on one or both of these areas until the printer cover tilts.

3. When the printer cover is tilted up, lift it completely off.

4. Push down on the right side of ribbon cartridge where it is marked “PUSH”. Remove the cartridge.

66666

5. Install new cartridge. Be sure the ink cartridge is inserted firmly to prevent weak or irregular printing.

The cartridge must be properly seated and aligned for best printing.

6. Turn the cartridge “knob” (marked by an arrow) clockwise to stretch the ribbon.

If you get ribbon ink on the printer case, wipe it off immediately.

Once it dries it is difficult to remove.

7. Replace the cover.

8. Replace the paper.

You may insert the ribbon cartridge if there is already paper in the printer.

77777

Hold the cartridge as shown above and slide it over the paper and into the printer compartment. Be sure the paper goes between the ribbon cartridge and the ink ribbon.

Printer Test and Setup

The printer can be tested and setup using the steps described in this section. Testing and setup are done using the rocker switch on the printer.

rinter T est

With the printer unplugged at the outlet or at the back of the printer, press and hold the right side of switch as you plug the unit in. The printer will print out a list of the configuration as it currently exists then do a continuous print test. To stop the print test, press either side of the rocker switch. Below is a sample of what is printed when you do the print test.

Accessing the Setup

Menu

To access the setup menu follow these steps:

1. Unplug the printer either at the outlet or at the back of the printer.

2. Press and hold down the left side of the rocker switch and plug in the printer. The printer will advance the paper. After the paper advance has stopped, count for

3 to 5 seconds and then release the switch. The following is printed:

Back Space

Code 8

Upon receipt of this code, the printer erases from its buffer the previously received character. This is useful in correcting typing errors for programs that send data both to a video screen and the hardcopy printer. Remember that if you type more characters than the printer can print on a line, the printer will automatically start printing.

Line Feed

Code 10

The printer handles this control code in exactly the same manner as carriage return (control code 13) except when a line feed immediately follows a carriage return. The line feed code is ignored if it is immediately preceded by a carriage return. The default setting is 7.6 lines per inch.

Carriage Return

Code 13

Whenever a carriage return code is received, the printer will print out the current contents of its buffer, then clear the buffer to get ready for additional data.

Double Height

Code 14

This control code tells the printer to switch to the double height character line. The control code can be sent at any time on a line; it need not be the first code received by the printer after a carriage return.

You cannot mix normal and double height characters on the same line. Once you select the double height, the printer will remain in that mode until it receives a carriage return or line feed. A line print caused by a buffer full condition will not clear the double height command. This means that the “wrap around” print line will also be double height if the double height command was sent before the line buffer was filled.

Double Width

Code 15

This control code tells the printer to switch to double width character printing. The control code should be sent as the first character on a line. If it is received after half the maximum characters per line were sent then the printer will ignore all characters on the last half of the line.

You cannot mix normal and double width characters on the same line. Once you select the double width, the printer will remain in that mode until it receives a carriage return or line feed. A line print caused by a buffer full condition will not clear the double width command. This means that the “wrap around” print line will also be double width if the double width command was sent before the line buffer was filled.

Enlarged P rinting

Codes 14 and 15

Enlarged printing may be selected by sending both the double height command (control code 14) and the double width command (control code 15). The control codes may be sent in either order, but because of the double width restrictions, the codes should be sent at the beginning of a line.

Example of Control Codes 14 and 15:

Reset Sequence

Number ode

1 nhibit Line Spacing ode

When the printer receives this control code it will immediately reset the sequence number to 00000.

A standard character line is made up of ten dot lines. Eight of these dot lines are used for the printable character and two are used for space between lines. When using character graphics it is desirable to eliminate the two blank lines so the graphic characters connect together.

Sending a CHR$(17) (control code 17) anywhere on a line of data will stop the printer from putting space between that line and the next. If a CHR$(17) is not on a print line, the normal space between lines will be printed.

Dot Graphics

Code 18

The mechanism used in the printer prints one line of dots across at a time. This means that when it prints one line of characters it has actually printed ten lines of dots where the first eight lines make up the character and the last two lines are blank for the space between character lines. By using the CHR$(18) control code, you can tell the printer which dots to print for one whole dot line. Since there are 144 dots per line, you must follow the CHR$(18) control code with 144 bits of information. For every place there is a one in the 144 bit pattern you send, the printer will print a dot. Rather than receive one bit at a time the printer expects to receive the information eight bits at a time. This means that after receiving a CHR$(18) the next eighteen 8 bit characters it receives will be printed as dots to form one dot line.

To figure out the dot pattern values to send after the

CHR$(18), you will need some grid paper. A large sheet with 144 grid boxes across would be convenient. If such a large sheet of paper is not available, you could divide your pattern in half and work with 72 grid boxes across. Divide up your grid paper by drawing a heavy line down every 8 boxes across. Now fill in each box of the grid that you want to be printed. Now do the following procedure to compute the eighteen values which describe your desired bit pattern.

Imagine placing the number sequence over each of the first eight grid boxes.

Now add together all the numbers above the boxes which are filled in or have a dot as in the example above. In our example, we would have 2 + 16 + 32 which equals 50.

‘50’ then would be the first entry of a data statement which would be followed by seventeen more numbers computed in the exact same manner as the example.

Once you have the eighteen values in a data statement, you need simply run a program which prints a CHR$(18) followed by the data value read from the data statement.

Don’t forget to end all of your print statements with semicolon. This will prevent carriage returns CHR$(13) from being sent, which would become part of the eighteen data values for which the printer is waiting.

Example 1:

Example 2:

User P rogrammable

Character

Code 19

By using CHR$(19) you enter the Custom Character mode.

This allows you to design and print your own 6 x 8 character by inputting data. A data statement is made of numbers that represent a row of dots which when read all together, will make up your character. To design your character, follow the example below. You should notice that each number in the data statement corresponds to one row in your character. To design a character, follow these steps:

1.

Use quad ruled paper to design your character.

2. Number 8 consecutive rows like this:

1

2

4

8

16

32

64

128

3. Now design your character in dot form (see the example below).

4. Add together all the numbers from the column on the left, counting only where you have placed a dot in a row. In our example, the first column has three dots located in rows 4, 8, and 16. Added together they equal 28.

5. Put your final total for each column into a data statement in column order.

The data statement in your program will read:

DATA 28, 34, 65, 65, 54, 34

The next step is to tell the printer your newly designed character. To do this you must send a CHR$(19) followed by the six numbers you computed above. Following is an example of how this can be done.

Set Time and Date

Control Code 20

After typing RUN, your custom character will be stored in the printer’s memory. It will retain this information until the printer is switched off or until you write over the data by defining a different character.

To print your newly designed character, simply send

CHR$(126) which corresponds to hexidecimal value 7E.

This control code is used when setting the printer’s time and date clock. Following is the text string to send when setting the clock:

Read Time and Date

Control Code 22

This control code is used to read the printer’s time and date clock. Following is the ASCII string received:

Cancel Reverse Field

Control Code 24

Sending this control code will turn off the reverse field mode that is selected using control code 25.

Reverse Field Control

Code 25

Send this control code to turn on the reverse field printing mode. This will print white letters on a dark background. Do not print more that three reverse field print lines. Also, do not print more than a few empty spaces in a reverse field. The printer may become overloaded and stop printing.

Selectable Column

Width

Codes 29, 30, 31

The printer powers up in the column mode last selected by configuration. You can change the column width by sending the appropriate control code from the list below:

Control code 29 - 24 columns

Control code 30 - 32 columns

Control code 31 - 40 columns

You can send the control code at any point on a line before the buffer becomes filled. You cannot change column widths on the same line.

The Model 122X printer can produce all ASCII characters from hex 20 through hex 7D (decimal 32 through 125).

Here’s what they look like:

Note the last two codes of the usual ASCII character set are not supported. Instead, if CHR$(126), which corresponds to hexadecimal 7E, is received by the 122X printer, it will print the character defined in its RAM (Random

Access Memory). The section on USER Programmable

Character describes how this RAM can be loaded with any 6 x 8 pattern.

The model 122X also has a graphic character set that resides between hexidecimal values 80 and FF (decimal

128 and 255). The symbols used are compatible with

Radio Shack® Model 100 portable computer.
