USB printing mangles printjob :-(

[Poul-Henning Kamp]

While testing my dads HP 880C printer, I found out that our USB printing
mangles printjobs.

I ran the "colorcir.ps" file through ghostscript with the hpijs driver
set to output for the 880C and saved the result in a file.

If I send that file to the printer via the parallel port, it prints
perfectly.  If I send it via USB/ulpt there are corrupted bytes in
the job which mess up the printout in various ways.

I don't have time to hunt this down.
