I have a HP DeskJet 3520. It's a USB printer. I'm running Slackware 10.1 with the 2.6.10 kernel. X is not installed since this is used as a server. I can setup my printer through CUPS via http://localhost:631. It doesn't show any errors. When I try to print a test page, it doesn't do anything. When I go into Completed Jobs, it says it was aborted. When I do: # touch test.txt # echo "Hello World" > test.txt # cat test.txt > /dev/usb/lp0 Nothing happens. lsmod shows this: Module Size Used by lp 8616 0 usblp 10944 0 parport_pc 24964 1 parport 32648 2 lp,parport_pc uhci_hcd 30160 0 usbcore 105464 3 usblp,uhci_hcd I have tried this command: foomatic-configure -s cups -p HP-DeskJet_3520 -c file:/dev/usb/lp0 -n HP -d hpijs And got the same results. The computer is an Everex Explora with an AMD 700 MHz. The chipset is a VIA VT82C686A. When I do lspci -v, I get this for USB: 00:07.2 USB Controller: VIA Technologies, Inc. VT6202 [USB 2.0 controller] (rev 0e) (prog-if 00 [UHCI]) Subsystem: VIA Technologies, Inc. (Wrong ID) USB Controller Flags: bus master, medium devsel, latency 64, IRQ 10 I/O ports at cc00 [size=32] Capabilities: [80] Power Management version 2 00:07.3 USB Controller: VIA Technologies, Inc.

(Wrong ID) USB Controller Flags: bus master, medium devsel, latency 64, IRQ 10 I/O ports at d000 [size=32] Capabilities: [80] Power Management version 2 I also have a copy of the error_log from cups, if you need it, I will post it.

I also know the printer works because I can print from my laptop if I plug it in directly. I'm also dual-booting my laptop and can print from within Slackware 10.1 on that.

The error_log is posted over at linuxquestions.org. Here's the link to that exact post: http://www.linuxquestions.org/questions/showthread.php?postid=1453077#post1453077

Have you tried the cupsdoprint command? eg: $ cupsdoprint test.txt
