The ImageMagick convert command can convert from almost anything to
almost anything else. For example, I have produced .tif files from
the .ps files produced by printtarg. But when converting from a raster
graphics format to postscript, it just incorporates the raster graphics
in the postscript file. No sophisticated raster to vector graphics is
attempted.
I actually printed the target .ps file using photoprint which accepts
postscript files. It uses gutenberg to print. At one time I understood
pretty much what gutenberg and cups did, but things have changed quite a
bit since then. Since my printer, an Epson 1280, is not a postscript
printer, at some point raster data has to be sent to it, but I'm not
sure when and how.
Gimp also accepts postscript files which of course it changes internally
to RGB pixels for editing. So I could print from that also. But I
believe the only way at present for me to incorporate a print profile
under Linux is to use photoprint.
Gutenberg supposedly allows all sorts of sophisticated controls when
printing, such as modifying each of the RGB curves separately, but it
doesn't use profiles yet.
