Hello, I have Fedora Core 3 kernel 2.6.9-1.667, HPG55 printer, hpG55.ppd, hpijs-1.6, and CUPS-1.1.22. Question #1-My BIOS asks if my operating system is a plug-and-play one. Yes or no? Question #2-My BIOS says If your operating system is OS/2 and main memory size over 64 MB select OS2, otherwise select Non-OS2. Which should I select? Question #3-In my BIOS I have selected the ECP mode for the Onboard Parallel Port. The ECP mode asks which Direct Memory Access channel, 3 or 1. Which should I select? Question #4-My HPG55 printer works fine in parallel hookup but does not print in usb hookup. lpinfo -v recognizes the printer as direct usb. lsusb shows Bus 002 Device 002:ID 03f0:0011 Hewlett-Packard. However /dev/usb/ file shows lp0 with 0 bytes and -rw- rw--- instead of crw-rw=== 1 lp sys 180. I think Fedora Core 3 is creating a regular lp0 file instead of a device node. What should I do now? Thanks for your help. Larry
