Couldn't get your command to run succesfully but this  sent a file to the printer (which hung it) and created an empty 4750-error.out file

nc 192.168.1.70 9100 <cups1-52_fail.ps >& 4750-fail.out

sending the same command with the 1-50-success file results in it printing and an empty .out file being created.

Thanks for all the help so far.  I did try installing cups 1-50 binary with poppler13 from the oneirix repositories.  This screwed up apt and also killed cups so I ended up reinstalling the OS.  I am now wondering if I should just create a virtualbox with oneiric server on it and run cups in that.  Then at least I should be able to print via the virtual box?
