Hi, 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] > lp0" i get nothing. Currently I'm using Fc4 with the latest 2.6.14 errata kernel but this condition occurs on all kernels. Any suggestions?
