"Error on 5766" (or some other number)

[gravelld]

I'm trying to print this document direct from Firefox: https://jtbd.info/2-what-is-jobs-to-be-done-jtbd-796b82081cca

If I try to print it directly, using the Firefox print dialog, I get "Error on (some number)". /var/log/syslog shows:

Aug 26 12:21:42 study-workstation dbus-daemon[3800]: [session uid=1000 pid=3800] Activating service name='org.boomaga' requested by ':1.162' (uid=1000 pid=8775 comm="/usr/lib/boomaga/boomagabackend 494 What is Jobs t" label="/usr/sbin/cupsd//third_party (enforce)")

If I print the file to a PDF instead, and then open that in boomaga, I get the same error message in boomaga, but syslog also shows:

I think this suggests the PDF is broken... but then directly printing the HTML appears broken too (or does this create an interim PDF?)

Ah yes, I was able to fix the corrupted PDF using ghostscript and then boomaga could open and print it.

So maybe Firefox is just generated bad PDFs - I'll leave this open but feel free to close.
