I upgraded from 1.10 to 1.12, using in both cases the
RedHat 7.x RPM. Under 1.10
, things print OK on my 710C, but almost nothing works
under 1.12. (I did remember to edit the new
pnm2ppa.conf!). calibrate_ppa piped into pnm2ppa and
then to lpr (as described in the documentation) still
works. But anything which I try to print through the
SuSE apsfilter fails completely. I also tried compiling
1.12 from source, but the result was the same.
I then tried simply replacing the version 1.10 binary with
the version 1.12 binary, leaving pnm2ppa.conf
unchanged. I printed something from StarOffice which
printed OK on 1.10, but nothing came out with the 1.12
binary. (The spool file was produced and processed, but
no printer output.) The only thing which changed was
the pnm2ppa binary.
