 Multiple queries produced different id0.txt files. All are attached.
No lp1 file existed at /dev/usb.

Re 14Jan12 message on use of the new backen - I interpreted "remove your
print queue" to mean remove pending documents. Not so sure that was
what was meant. Could it be that request was to remove all printer
configuration data from the operating system?

For info - I dusted off an old machine with a parallel port, installed
both Linux Mint and Ubuntu 11.0. No difficulties getting the printer
installed and working.

Many thanks for your assistance.
