Applications usually send print jobs in PDF, leading to a

pdftopdf -> gstoraster -> rasterto...

filter chain. gstoraster which uses Ghostscript can be replaced by
pdftoraster which is Poppler-based:

pdftopdf -> pdftoraster -> rasterto...

This can be done by editing the file
/usr/share/cups/mime/cupsfilters.convs, changing the line

application/vnd.cups-pdf        application/vnd.cups-raster     100
pdftoraster

to

application/vnd.cups-pdf        application/vnd.cups-raster     98
pdftoraster

Then gstoraster is not used any more but always pdftoraster instead.

There is also an imagetoraster filter which converts many image formats
into CUPS Raster, but this does not work with multi-page jobs.
