I have a Zebra QL420plus that when I print to it, it prints blank page. It is setup as Generic ASCII port 9100. I saw info about sending a .asc file to it before any print. Anyone have this info?
You might try setting up the queue for the Zebra using the hpjetdirect:
smit -> print spooling -> AIX print spooling -> add a print queue -> hpjetdirect -> other -> generic -> Do NOT make this system a BOOTP/TFTP server
Then I believe the Zebra uses PCL (The programming cod is ZPL or ZPL II Programming Language) so put your queue name in the PCL Emulation and fill in the hostname for the connect.
But one question is what is sending the data to the Zebra Printer. Is your program outputting in PCL or PostScript format. Or is it true ZPL code if it is ZPL then the queue needs to be a pass thru and no emulation.
