I've been trying to make a Dell 5110cn printer to work from Linux, to no avail.
I've tried sharing the printer from both a Linux and a Windows machine, and in either case, Windows clients can always print fine.
When a Linux client sends a print job that's larger than a few hundred KBs, the printer chokes and prints pages with what appear to be PostScript errors, like:
ERROR: ioerror OFFENDING COMMAND: image STACK: lot's of characters
I've been struggling with this for weeks now, and nowhere have I found an answer or a pointer.
