Sorry, Anne, you are wrong when you say that TrueType
fonts are interpreted as bitmaps in PDF files. According to
information that Adobe's in-house PostScript and PDF guru
Dov Isaacs has posted repeatedly on the Frameusers and
AcrobatTalk lists, all current AdobePS drivers convert TT
fonts into PostScript Type 42 fonts, which produce much
the same results in Acrobat as do Type 1 fonts (assuming
that the TrueType font itself is properly designed). If you're
interested in further details, I'm pretty sure I saved Dov's
most recent posting on this subject or you can check the
Frameusers list archive.
I'm guessing that some non-Adobe PostScript printer drivers
might not provide the TT-to-Type 42 conversion. In my
experience, reliable results in PDF conversion absolutely
requires the use of a PostScript printer driver instance
built with the latest appropriate version of the AdobePS
core driver (which varies with your OS) and the Adobe
Acrobat PPD (PostScript Printer Description) file. Using a
printer driver that is set up for some physical printer is
almost certain to cause PDF anomalies of some degree;
this is particularly true for recent HP printer drivers since
these printers use a PostScript emulation rather than true
Adobe PostScript.
Another thing that might be causing Kelli's problem is if
Georgia is a Type 2 PostScript font, because those fonts
are not handled well by Acrobat.
Finally, *all* Acrobat users should check is what specific
version they are using. Both Distiller 3.01 and Acrobat 4.0
had serious bugs. If you are using Acrobat 3.0, make sure
you are using Distiller 3.02 rather than 3.01; if not, go
immediately to the Adobe website and download the free,
foolproof 3.02 update. If you are using Acrobat 4.0, make
sure that you are using 4.05a or 4.05b. If not, contact
Adobe to obtain the CD for the latest version. And if you
have 4.05a, you should visit the Adobe website to get the
latest update for that version.
