WP-233 Printer User’s Manual
Introduction The Model WP-233 dot matrix printer has one of these electrical interfaces: RS-232 Current Loop This manual is split into the following main sections: • • • • • • Introduction Installation Operation Maintenance Printer Test and Setup Communication Installation Please 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.
3. Unroll several inches of the paper. 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.
. Slide the paper through the slot in the printer cover. 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 so as 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. To Remove the Paper Roll 1. Advance the paper about one inch beyond the paper cutter by using the Paper Feed switch. 2.
Operation Connecting and Powering up and Your Printer For DC modified units supplied with cable, connect positive voltage to striped wire. See the DC power connection illustration below: 1. Attach the appropriate cable between the printer and your indicator. 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.
If your printer is used infrequently, the print impression may become weak because the ribbon dried out. To advance the ribbon to a new section, hold down the Paper Feed switch for several seconds. Changing the Printer Ribbon 12 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.
Inserting a Ribbon with Paper in the Printer If you get ribbon ink on the printer case, wipe it off immediately. Once it dries it is difficult to remove. 5. Install 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. 7. Replace the cover. 8. Replace the paper.
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. Printer Test 14 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.
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 3-5 seconds and release the switch. The following is printed: If you wait less than three or more than five seconds Ready. . .
With the printer in the setup menu and with CONFIGURE . . . [NEXT/OK] as the last item printed, press OK (right side) to access the configure menu. The following is printed: Load Defaults LOAD DEFAULTS gives you the opportunity to reset the printer to all default settings (shown below). Choose OK to do this or NEXT to go to the next parameter. The following is printed: Baud rate is the next parameter you can set in the configure menu.

Your choices (with examples) are NONE DOUBLE WIDE DOUBLE HIGH DOUBLE WIDE/HIGH After you choose one of the magnifications the printer will print Ready. . . to show the printer is out of the configuration menu and the setup menu and is ready to print. CUSTOM. . . 18 The next setup menu item after CONFIGURE. . . is CUSTOM. . .. With the printer in the setup menu and with CUSTOM. . .
If you press OK the printer will print the current custom setup. A sample is shown below. This manual assumes the time and date option are installed and operating. If you do not have this option you will not see references to the clock or date listed in most menus. This printout shows you how each item is currently set. Below is an explanation of each item and the choices you can make for each. T/D Format This feature is available only on units with the time/ date option installed.
Auto T&D AUTO TIME AND DATE is the next parameter. Your choices are YES - autoprint after CR (carriage return) NO - do not autoprint after CR Auto Seq# AUTO SEQUENCE NUMBER is the next parameter. Choose NO - don’t autoprint sequence number after CR YES - do autoprint sequence number after CR Zero ZERO is the next parameter. Choose how you want the zero character to look in your printouts. Choose between 0 and 0. Pound Sign POUND SIGN is the next parameter.
XON/XOFF Ext Ch Set The choice to use the extended character set is available only when 8 data bits are chosen. Print Ready XON/XOFF is next. Choices: 90/10 - The printer will send an XOFF when the buffer is 90% full. As the buffer empties the printer will send an XON when the buffer reaches 10% of capacity 90/80 - XOFF is sent at 90% and XON sent at 80%. EXT CH SET is next. This stands for Extended Character Set.
SETCLOCK. . . This feature is available only on units with the time/ date option installed. The next item in the Setup Menu is SET CLOCK. . . With the printer in the setup menu and with SET CLOCK. . . as the last item printed, if you press OK (right side) the printer will print the following: The printout shows the year currently in memory. The 9 is reversed (white on black) to show the position of the cursor. This is the number which will be incremented if NEXT (left side) is pressed.
When you have completed the SET DATE menu the following is printed automatically: Choose NEXT (left side) to increment the number or OK (right side) to accept the 1. Repeat this same procedure for hours and minutes as shown below. When everything is as you want it and you press OK, START CLOCK is printed. Press OK (right side) to start the clock. The printer then prints Ready. . . showing you that it is out of the setup menu and ready to print. RESET SEQ# RESET SEQ# is the last setup menu item.

CONTROL CODES According to the American Standard Code of Information Interchange (ASCII), there are 32 control codes in addition to the codes for the printable characters. (Control codes are sent as data, but the receiving device interprets them as abbreviated ‘’instructions”, communication - status messages, etc.) The printer recognizes these control codes: Function Reserved Reserved Reserved Back Space Line Feed Carriage Return Double Height Double Width Reset Seq.
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.
around” print line will also be double width if the double width command was sent before the line buffer was filled. Enlarged Printing Codes 14 and 15 Enlarged printing may be selected by sending both the double height command (code 14) and the double width command (control 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.
Dot Graphics Code 18 The mechanism used in 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$(18) control code, you can tell the printer which dots to print for one whole dot line.
Example 1: Example 2: User Programmable Character Code 19 By using CHR$(1) 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.
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.
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. Set Time and Date Control Code 20 This control code is used when setting the printer’s time and date clock.
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.
Default Table Below is a table showing the possible values for the Custom and Configuration menu parameters. The values shown in bold type are the default settings.
