PS files routed through a unix print server and on to a networked
HP4250 used to print fine but now fail with an undefined pjl error.
These same files print fine on a HP2300. Diagnostics/testing with the
unix jetdirect printer utility shows nothing wrong and succesfully
prints it's test ps file. Printer control panel tests show nothing
wrong at the printer. I'm new to the unix environment and have stumbled

around for a few days. What are your thoughts (about the print problem,

not my stumbling)
