I'm not sure if this is a hardware or software problem but I cannot print to by hp deskjet 550c anymore. I has not been working for a while and I don't know when or what caused it to stop working. When I plug my 550c into the parallel port the busy light stay on and nothing prints. Is there any parallel port configurations that need to be done? I have upgraded the kernel from a redhat 5.1 several times (2.2.14 is where i'm at). Is there any special compile options to be aware of? I did include just about anything having todo with prallel port and printers... thanks
