did not see your reply to just now. I can report I am now printing on usb canon. Ink for Epson dried up but reported job complete. As I am pensioner, I am binning the Epson as it was a basic printer to begin with and its actually cheaper to buy a new printer than buy refills.
ON 32 bit Not sure if I needed to but re-compiled gtk2 and gutenprint and then re-compiled ghostscript without recompiling anything else, altho I can see cups-filters might get my attention.
strings /usr/local/bin/gs | grep libidn
tc@box:~/Downloads$
If you would like to re-compile ghostscript, I used
SRC=ghostscript-9.52
compiletc wget squashfs-tools zsync xz cups-dev cairo-dev libjpeg-turbo-dev lcms2-dev libXt-dev
# libXt-dev not detected until make
cd $SRC
rm -rf expat freetype lcms2mt jpeg libpng
./configure --prefix=/usr/local --with-system-libtiff --localstatedir=/var --enable-dynamic --disable-compile-inits
make -j5 takes 3.5 minutes
dep list modest change to remove libtiff as we are using GS
libcups.tcz
lcms2.tcz
fontconfig.tcz
libpng.tcz
If you do not have time, depending on your priorities, would you like me to submit a TCE
I promise I will re-check my crap. But I can see this pdf test is a pass
