Thanks for your help, I don't really know why I keep missing the obvious :P
I've now compiled the pstocanonij you suggested, but unfortunately:
Jun 20 21:23:51 heisenbug cupsd[21991]: pstocanonij:
/home/nawal/.nix-profile/bin//gs -sstdout=%stderr -r600 -g4958x7016 -q
-dNOPROMPT -dSAFER -sDEVICE=ppmraw -sOutputFile=%stdout -|
/home/nawal/.nix-profile/bin//cifmp250 --imageres 600 --papersize a4
--media plain --paperload asf --bbox 9,14,586,834 --fit --copies 1
Jun 20 21:23:51 heisenbug cupsd[21991]: Error: invalid printer model name
Jun 20 21:23:51 heisenbug cupsd[21991]: Read 324 bytes of back-channel
data...
Jun 20 21:23:52 heisenbug cupsd[21991]: Wrote 1 pages...
Jun 20 21:23:52 heisenbug cupsd[21991]: PID 30211 (pstops) exited with no
errors.
[nawal@heisenbug:~/data/nixos/user/pkgs/canon]$ grep "invalid printer model
name" -R ./cnijfilter-common/cnijfilter-3.40/src/bjfoption.c
fprintf(stderr, "Error: invalid printer model name\n");
A bit of googling suggests the "model name" isn't quite what's in the ppd
file...
[nawal@heisenbug:~/data/nixos/user/pkgs/canon]$ grep Name -R ./usr/| grep
ppd | grep Model
./usr/share/ppd/canonmp250.ppd:*ModelName: "Canon MP250 series"
I think this might be where I leave the rabbit hole...
