newsCUPS+Gutenprint printing fixed
I reported yesterday that printing to my Canon MX310 printer does
not work, using the CUPS+Gutenprint driver (which is what the CUPS web
interface automatically selects):
http://bkhome.org/news/201812/canon-mx310-mfp-rescued-from-road-verge.html
The error-log showed "gs: no such file or directory", which I thought
that I had fixed by creating a symlink, but no, the error is still in
the log. But, ghostscript is installed, and 'gs' is there, at
/usr/bin/gs.
Then a thought occurred: 'cups-filters' is compiled in 'oe-qky-src',
my fork of OpenEmbedded. The 'ghostscript' package in oe-qky-src does
not install 'gs', it installs 'gsc' and it is in Woof where I create a
symlink, 'gs' to 'gsc'.
It could be that during configuration of the source, cups-filters cannot
determine where 'gs' is and this is causing the failure to find it in
the running EasyOS.
Anyway, I compiled the latest 'cups-filters', version 1.21.5, which
also required 'qpdf' to be bumped to 8.2.1, and yay, printing works!
I have made both of those into PETs, which will be used in the next
release, 0.9.11, but soon will have to go back to oe-qky-src and sort
out what has gone wrong with configuring cups-filters.
So, good news. I am very tempted to buy ink cartridges, just so that I can see something printing! Officeworks has them:

...they are black. Duo, black and tri-colour cartridges:

Some inkjet printers won't work with only a black cartridge, which
was the situation with mine 10 years go -- a nasty trick by the
manufacture. Hopefully the Canon will print with just the black
cartridge, so I would have to spend AU$35 ...that would be an
indulgence, as I hardly ever need to print these days.
EDIT 20181210:
Have updated and recompiled 'ghostscript', 'poppler', 'qpdf' and 'cups-filters' in oe-qky-src:
https://github.com/bkauler/oe-qky-src/commits/master
...and built a pre-release of Easy 0.9.11, printing to the Canon MX310 works. So, no need to use the PETs.
