[cups] Cups failure?/

[Nicolas Schmidt]

I also had some trouble with getting a usb printer to work with cups. In the end it turned out that this was due to some interference between a USB printer kernel driver (ulpt) and the libusb library used by cups. The fix was to recompile the kernel without the driver, although there seems to be another workaround (see Johannes Meixner’s answer to my question on this list). To see whether your problem is due to the ulpt+libusb issue, check your dmesg to see if the kernel recognizes the printer and assigns it e.g. to /dev/ulpt0. Then do

echo „test“ > /dev/ulpt0’

If your printer doesn’t print, then something else is amiss. If it does however, try recompiling your kernel without ulpt and try again.

Best,
Nicolas A. Schmidt

The same unit has worked before in this distro and other unix distros but for some reason now all seems to be going well but no printing.  A snip from the most recent attempt at printing is included and i need help deciphering it. It seems that for some reason the data cannot be sent to printer....why ?!  thanks in advance for any help.
