Printing from Okular / ps printing

[gustaphe]

When printing from Okular, the files turn up but show as "Unable to load document" on the ReMarkable. The same file, sent through lp filename.pdf -d reMarkable works fine.

I did some digging, and it appears Okular sends ps files, rather than pdf (as in, sudo pdfinfo /var/spool/cups/<id of job printed with lp> shows a bunch of pdf info, but sudo pdfinfo /var/spool/cups/<job from okular> errors out, and ${5} contains document-name-supplied=okular_<name>.ps).

I got it working with

if pdfinfo "${jobfile}" > /dev/null ; then
    cp "${jobfile}" "${outname}"
else
    ps2pdf "${jobfile}" "${outname}"
fi

instead of cat ${jobfile} > ${outname}.

but it's a bit of a hack (it assumes that the file is either pdf or a ps). Printing is pure magic to me, so I don't know if there's a good way to do this.

Just thought I'd share in case anyone else needs this (or has a better idea for how to solve it).
