The CUPS book has examples (available on the site), and
you can look at Gutenprint, the DDK drivers, the sample drivers in
the CUPS sources, etc.

PCL3GUI shares some of the heritage of PCL5, however the raster setup
and compression modes are different.  Looking at the HPLIP sources
will provide some hints for your particular printer (and it *is*
highly printer specific...)
