Pascal, Output from USB Printer Detection is listed below.
There is one interesting thing that I have noticed in the output. In the last section of the output, the "/dev/lp0" is associated with "direct parallel". This is probably a CUPS error. Although my HP Laserjet 4 is actually connected to a USB port and nothing is connected to the parallel port, CUPS seems to falsely and erroneously think that it is a parallel printer. Anyway, as an experiment, I navigated to System > Administration > Printing and tried to add my HP Laserjet 4 as a parallel printer, even though it was actually connected to a USB port. Although it accepted my printer as a parallel printer and I was able to create an entry for it, I was unable to actually print out any documents because the printing process would always freeze or hang in suspension with a "pending" or "processing" status. The printing job would never go to completion or finish. *************************************************************************** toy...@xw8200:~$ lsmod | grep usb usblp 12407 0 usbhid 40988 0 hid 83376 1 usbhid toy...@xw8200:~$ tail -f /var/log/messages Apr 18 09:37:18 xw8200 rsyslogd: [origin software="rsyslogd" swVersion="4.2.0" x-pid="605" x-info="http://www.rsyslog.com";] rsyslogd was HUPed, type 'lightweight'.
