This helps a little bit, but not every printing jobs.
If you just need to print text to this printer via CUPS,
you do not need any filter or (may not need a pdd either,
but I need to verify it). By default, CUPS convert text to postscript,
then to printer coded file via a proper pdd filter.
That you got errors may be because your printer probably received
a postscript coded file or even further converted to some common HP
coded file, which may not suitable for every HP printer.
To remove a text filter, either change /usr/local/etc/cups/mime.convs
something like
application/vnd.cups-text 0 texttops
to
application/vnd.cups-text 0 -
"-" means do nothing;
or change /usr/local/libexec/cups/filter/texttops
mv texttops text2ps
echo "cat -" > texttops
chmod +x texttops
If this works, this only fixes your text print problem. You may still not be
able to print other files, such graphics or postscript files.
You need to find a proper filter for this printer, maybe try it via
"gs -sDEVICE=ijs --sOutputFile=/tmp/test A_POSTSCRIPT_FILE"
or other filters (in -sDEVICE= line) to convert a postscript file to
/tmp/test file,
and try to print /tmp/test file to your printer via lpr command.
If you can find a working filter in gs, then find a match filter in CUPS.
Then reverse the change made above back, and install proper pdd for CUPS.
