•
Ensure the data stream is correct (all letters of command codes are in upper case and
without spaces).
•
Ensure the Baud rate, Parity, Data Bits, and Stop Bits are consistent with that of computer.
Print a Configuration Test Label to determine the RS232 settings.
•
Ensure the printer is recieving from the computer using the Hex Dump Mode. 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.
While checking the hex dump printout, look for OD
h
OA
h
(carriage return and line feed)
characters throughout. The command string should be continuous. CR or LF charcters are
not allowed between the start command (<ESC>A) and the stop command (<ESC>Z). If
Basic is being used, it may be adding these characters automatically as the line wraps.
Adding a width statement to your program can help suppress these extra OD
H
OA
H
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.
PRINT TEST LABEL
The contents of the Print Buffer can be examined using the Hex Dump mode. In the left column,
each line of data received is numbered. The center column provides the data in hexadecimal
format. And in the right column, the same data is provided in the ASC II format. Follow the
instructions below for guidance.
1 Power off the printer (if on).
2 Place the DSW1-6 switch in the ON position.
3 Place the DSW1-7 switch in the OFF position.
4 Place the DSW1-8 switch in the ON position.
5 Power on the printer.
6 Print a diagnostic label.
7 Turn the printer off and then back on to return to the normal print mode.
8 Return switch DSW1-8 to the OFF position.
9 Return switch DSW1-7 to the ON position.
10 Return switch DSW1-6 to the OFF position.
NOTE: A small label may produce a large amount of data when printed in
Hex Dump.
