I'm having trouble understanding what you wrote. > Since 2.4.0 there have been problems with my usb printer failing to > print at times, when this happens if i reboot the box it still won't > print, however if i reboot the box with the printer power off and then > power up the printer after the OS is fully booted it will print (for a > while) if i do a "cat [text file] > /dev/usb/usblp" i get nothing. In that run-on sentence you said: when you reboot you can't print, when you reboot you can print, and if you send a file to the printer with "cat" it doesn't print. It's hard to know what this means. > Currently I'm using Fc4 with the latest 2.6.14 errata kernel but this > condition occurs on all kernels. Any suggestions? Focus on a simple test case. For example, turn the printer power off, reboot, turn the printer power on, then use "cat" to send a file to the printer. Does the file get printed? Does the "cat" program hang? If "cat" does hang, what does Alt-SysRq-T show? What does the dmesg log show starting from the time you turned on the printer?
