I have many LJ4's connected serially through 3-wire DTC ports at 9600
baud. On some of the printers, I randomly (not consistently) receive
'22 SER IO ERROR' on the printer's display. Help! What do I need to
change to eliminate this error.
Most of the printers have JetDirect Cards for Netware printing. All
printers are < 300' from a DTC.
The errors occur mostly on output containing laser forms. But the
errors are not consistent. I have another LJ4 serially connected that
is my heavy-duty laser forms printer and it never receives a '22 SER
IO ERROR', but it also does NOT have a JetDirect card.
Any suggestions will be most appreciated!
