A binary package containing PPDs for PostScript printers is a printer
driver, the driver for the PostScript mode of these printers. Note that
a PostScript printer driver usually consists of only PPD files.
A printer driver package has to contain at least PPDs (the files itself,
the PPDs pyppd-compressed, or a PPD generator, either an executable in
/usr/lib/cups/driver/ or a .drv file in /usr/share/cups/drv/) and the
PPD updater for these PPDs (to update PPDs of existing queues, either in
postinst script or a file in /usr/share/cups/ppd-updaters/). In
addition, it must contain all filters specified in the cupsFilter lines
of the PPDs and their dependencies or depend on the packages containing
My suggestion is to create a new binary package named
printer-driver-postscript-hp containing the pyppd-compressed PostScript
PPD files (move from hplip-data) plus the PPD updater (move from hplip)
to get consistency. The driver name for this new package is
Postscript-HP (to be consistent with PostScript driver entry names on
OpenPrinting) and not hplip any more, so the files should have
printer-driver-postscript-hp should recommend the hplip package, as
hplip gives extra functionality (like toner level check) to the
PostScript printers but the printers work also without the hplip package
installed. There are no PostScript PPDs with valid cupsFilter lines
requiring filter executables from the hplip package.

Lets name the "new" driver Postscript-HP and the package
printer-driver-postscript-hp, to be consistent with OpenPrinting.

OK, the hpijs-ppds package is not part of the standard CUPS printing
environment, so we do not rename it.

OK, please provide a new patch. Thanks you very much.
