Greetings,
Now I understand what's happened.
I vaguely remember (probably several years ago now) working with ghostscript
to get font names to match what qt was producing. I seem to remember making
a whole set of aliases by printing samples from a kde app over and over again
with different fonts and then looking to see what qt called those fonts and
trying to find what ghostscript was calling them. I remember this process as
being quite horrible. [If I may be permitted a brief, possibly incorrect,
and definitely on the wrong list, rant: Why, in God's name, can't ghostscript
tell you what fonts it knows about? For example, why isn't there something
like "gs --print_sample_fonts > test.ps" which would cause ghostscript to
print a sample of every font it knows about, along with the names that
ghostscript knows for each font. Sorry for that, I feel better now.]
Anyway, I guess that at some point the qt default switched to embedded fonts
and that's when I started having problems with poor print quality. I just
turned off font embedding in qt (use qtconfig from the command line and look
on the printer tab). I can't say whether the font names qt produces match
what ghostscript might know about on any given system (I still have the old
aliases I made lying around on mine) - at the very least ghostscript will
have to know about your TrueType fonts (I think ttmkfdir is involved but I
don't remember for sure) At any rate, printing from qt (and thus kde) apps
here is now fine with embedding turned off.
I really hope that Trolltech makes fixing this problem a priority, as in
environments such as mine, quality text printing is absolutely essential, and
a problem like this literally - if this workaround didn't work - would
prevent us from using kde... And using unembedded fonts is really hard
(ghostscript's documentation is not much help). Don't get me wrong - I love
qt, it's by far my favorite toolkit, this just seems like a pretty big
problem right now.
Much thanks to everyone who suggested solutions, I'd have never figured this
out on my own. Oh and sorry for the rant above.
Mark
