Hi Till, thanks for your explanations.

Can you tell me how your divined that from just the description line, which doesn't mention PCL-6 ? Is it just from your experience with all this stuff? I've read enough that I understand foomatic usually provides a "generic" postscript PPD but I don't recall seeing any description of pxlcolor. I was wondering if PCL drivers could be used with clients sending postscript. It seems (for a modern enough revision of PCL) this is possible. Great. >> My question is - are there tools available to compare the capabilities >> offered by different PPD files, so I can make an informed choice? > > Not really tools to compare, but you can use the different modes of the > cupstestppd and lpoptions commands to get information about the PPD files. That's useful, thank you. I'll have a play with this. >> Most PPD auto generators in /usr/lib/cups/driver/ are simply >> self-extracting archives, others are generated from >> /usr/share/cups/drv/*.drv files. I have a related question about ppd locations but I'll start a separate thread for that. > The "(recommended)" is simply an entry in the *NickName lines of the PPD > files. For your printer the (recommended) is in the native PostScript PPD. Oh. I thought there might be some kind of automatic recommending based on the openprinting.org ratings of the various drivers. So the manufacturers usually set this in the *NickName lines, yes? Or do openprinting.org, or you (debian/ubuntu) guys? I'm seeking to understand the decision process so can figure out how to select one PPD over another, in the general case. > "lpinfo -m" calls all PPD generators in /usr/lib/cups/driver/ without > command line parameters ... Nice. (For those reading along, I tried this and found I needed to give the word 'list' as an argument, but the lists then duly appear.)
