PARALLEL INTERFACE TROUBLESHOOTING

•Ensure the printer cable is thoroughly connected to the correct PC and printer ports.

CAUTION: NEVER CONNECT OR DISCONNECT INTERFACE CABLES (OR USE A SWITCH BOX) WITH POWER APPLIED TO EITHER THE PRINTER OR THE HOST. THIS MAY CAUSE DAMAGE TO THE INTER- FACE CIRCUITRY AND IS NOT COVERED BY WARRANTY.

•Ensure the printer cable (IEEE1284) meets specifications. The computer may not be able to communicate correctly otherwise.

•Ensure the Interface Module is installed.

•Ensure the data stream is correct, all letters of command codes are in upper case, and without spaces.

•Ensure protocol codes are set for standard or non-standard and that they are consistant with the data stream.

•Ensure the printer is recieving from the computer using a Recieve Buffer Hex Dump. Refer to that procedure for instructions. The printer will print (only once) a hexadecimal dump of everything it has received from the host computer. Each hexadecimal character represents a character the printer received. Analyze and troubleshoot the data stream.

NOTE: A small label may produce a large amount of data when printed in

Hex Dump.

While checking the hex dump printout, look for ODH OAH (carriage return and line feed) characters throughout. The command string should be continuous. CR or LF charcters are not allowed between the start start command (<ESC>A) and the stop command (<ESC>Z). If Basic is being used, it may be adding these characters automaticlly as the line wraps. Adding a width statement to your program can help suppress these extra ODH OAH characters by expanding the line length up to 255 characters.

If not programming in BASIC, check to see if the equivalent statement in language exists to suppress extra carriage returns and line feeds from data being sent to the printer. The data stream must be one complete line going to the printer.
