• The first five characters are the printer command string delimiter <STX>.
If <STX> is missing, the printer will not respond to any commands.
Characters before <STX> are filtered out.
• The next characters you see are printer commands and data. Here are
some examples:
The final characters of the printer command string form the Print
command:
Look for invalid printer commands or incorrect syntax within the printer
command string.
• The last five characters printed are the final delimiter of the printer
command string <ETX>. If <ETX> is missing, no data will be sent to the
printer from the twinax interface. Characters following <ETX> are
filtered out.
5. Print the data from the final stage of processing. Without switching off the
printer, set the twinax interface rear panel switches back to the original
setting you recorded in Step 2.
6. Run the print program on the host. The printer prints each character that is
not filtered out by the twinax interface.
At this stage in the processing, all the host protocol characters have been
removed, the EBCDIC code has been converted to ASCII code, the ASCII
control code mnemonics have been converted to actual ASCII control codes,
and characters outside of printer command delimiters have been filtered out.
There should not be any characters other than the printer commands. If you
see any characters that are not printer commands, you should suspect they
are causing printing problems.
