Some days ago, I have released cups-filters 1.0.43. It improves a lot on
PPD-less printing:

- PPD-less PCL 5c/e printing with rastertopclx, in grayscale and color
- PPD-less PostScript printing with pdftops, duplex, resolution, input
  tray, color mode, and make/model (for quirk rules) can now be
  supplied by the command line
- pdftoippprinter switches to Poppler-based pdftoraster if Ghostscript
  is not present, eliminating need of Ghostscript for PPD-less printing
- gstoraster and pdftoraster are capable to output PWG Raster
- Support unprintable margins supplying them on the command line via
  "media-left-margin", "media-right-margin", "media-bottom-margin", and
  "media-top-margin" (in 1/100th of a mm).
- Handle options duplex/sides, fit-to-page/fitplot, orientation-
  requested/landscape correctly when printing PPD-less
- A lot of bug fixes.

I also had to fix a bug in Poppler, see

https://bugs.freedesktop.org/show_bug.cgi?id=72312

This should allow PPD-less printing on most supported printers now. Bug
reports and patches are welcome.
