Description Tim Waugh 2006-10-30 11:31:49 EST
Description of problem:
See upstream bug report:


The parallel backend opens the device node with O_WRONLY, but then calls
backendRunLoop with use_bc=1, causing it to try reading from the file
descriptor.  Of course this fails, but unfortunately it can produce busy-looping
when the printer is off or busy.
