How about writing a program to create a PPD file automatically by

This would be great, but how do they do this, I only know how to
retreive PJL options from a PJL-capable printer. See the
foomatic-getpjloptions script of the foomatic-db-engine package on
linuxprinting.org:
http://www.linuxprinting.org/cvsweb.cgi/~checkout~/foomatic-db-engine/foomatic-getpjloptions.in?rev=3.0content-type=text/plain
but only a small part of the printer's options are PJL options (for
example PageSize and Resolution are usually PostScript commands to
insert in the job data) and some printers (as the Brother HL-5040) do
not answer to the script.
See attached files. This is as far as I got.
If there is no way to detect some printer features via PostScript, one could
think about using SNMP.
I think Adobe had or has something like this. One sees references to
it in the comments of some PPD files.
Did they somewhere publish the protocols for this?
All the stuff I'm using is in the PostScript spec.
If you want to write such a tool, join the Foomatic project and then one
can make a queue for a PostScript printer simply with
foomatic-configure, without needing to have a PPD file or the Foomatic
database installed.
I might be interested if the project is really feasible.
Some of the commercial PPDs seem _way_ more complicated than they need
to be.
Some manufacturer's, as HP, have implemented some options completely in
PostScript (as N-up or watermarks), so to the appropriate option choices
not simple PostScript commands but complete subroutines are assigned.
But HP's PPDs on http://www.linuxprinting.org/download/PPD/ are free
software, so one can rip out this code and paste it into another PPD
(for example of an Epson printer) to add these options there. I have
already accidentally created a print queue for an Epson AcuLaser C2000
PS using HP´s PPD file for the HP LaserJet 4050, and HP´s N-up option
worked nicely on the AcuLaser. If I had Epson´s PPD and pasted the N-up
option there I would have it even in color, but I didn´t find Epson´s PPD.
A sore point.
I have to carefully remove HP's N-up code from their PPD files because it
interferes with my use of EndPage to implement my banner page alternative.
Why does HP go to all the trouble to implement a feature which is already
implemented in the fine Adobe PostScript driver without pre-empting everyone
else's use of EndPage?
