Did you restart/repower the printer, before trying to print? What document format is being used on /dev/ulpt? Maybe you have to use another format. Did you use the correct PPD file for your printer? I have a brother printer here which uses USB, and claims to support PCL 6, but whenever I print something in PCL 6, it's not recognized. I found out I had to download a special PPD file, and install foomatic-rip, for cups. Then it worked using the GDI protocol. --HPSReceived on Sun Jul 12 2009 - 05:52:57 UTC
