When OSX exhibits printer problems.
1] verify the printer drivers are current.
2] Delete the instance of the printer, Add the printer back.
This works a large percentage of the time.
If the computer is talking directly to the printer and not to a print server or spooler.
Corrupt font caches can cause this, but is unlikely because the caches are found on each machine.
It is possible that one or more of the databases has corrupt font information. I have recently run into this in a FMP 5.5 to FMP 10 conversion. Did you get any errors on conversion? Did you convert with FMP Advanced or FMP?
Any fields display <unknown font> errors?
There is a printing system repair utility called
Print Therapy 6.0.7 LE - (Leopard) repair printing system problems
OSX isn't the problem. I could print just fine with all other apps on these computers including FMP6. I only had problems printing with FMP/FMPA 8.5. I, too, started to focus on font compatibility issues since fonts also seemed to be related to a previous problem I was having with saving to pdf ONLY on FMP 8.5 and no other app, until I finally hacked an FMPA config file to make saving to pdf work!
Turns out I just came across the Gutenprint drivers, and preliminary tests indicate that those pearls might have just solved all my printing problems. Unbelievable.
Thanks for your assistance.
