Comment 22 for bug 277404

To easily reproduce the problem do (d00022-001 is PDF printing output of gedit, captured from the spool directory of CUPS):

wget http://launchpadlibrarian.net/21294491/d00022-001
pdftops -level3 -paper A4 d00022-001 > l3.ps
pdftops -level2 -paper A4 d00022-001 > l2.ps
pdftops -level2 -noembtt -paper A4 d00022-001 > l2noembtt.ps

Then send the files unfiltered to a PostScript printer from HP (Ghostscript displays all files correctly on the screen). The l3.ps prints some characters as squares, the l2*.ps print correctly. This means that something is broken with the Level 3 PostScript output, at least for HP printers.

The HP LaserJet P3005 even crashes on the faulty PostScript Level3 output of pdftops.

See

for the broken output of l3.ps.
