Do you mean /usr/lib/cups/backend/hp? It's a part of HPLIP debian package:

Package: hplip
Version: 3.11.5-1.1
Installed-Size: 544
Maintainer: Debian HPIJS and HPLIP maintainers <pkg-hpijs-devel at lists.alioth.debian.org>
Architecture: i386

I posted the PPD that appears in the log:

D [13/Sep/2011:18:49:46 +0200] [Job 2778] envp[20]="PPD=/etc/cups/ppd/LaserJet.ppd"

The PPD file has the same created date of when I changed PPD from PCL3 to PS on cups http interface.

Ach! I should use FPDF (an pdf creator opensource php library) to generated the pdf file passed on STDIN to lp.

Ok, now I made other two test (using lp command this time), one with an normal multi pages pdf document and another with the FPDF one:

normal -> http://pastebin.com/Kz7cq2vp
fpdf -> http://pastebin.com/mthrQF2q

Both logs are different from the first that I posted, and the fpdf one has the issue, but why?

Thanks for your time Helge.
