Thank you for your post.
If printing works on one computer and not another, you will need to find out what are the differences between the two systems. If you believe it is a printer driver issue, copy the printer driver from the working computer and install it on the not working computer. Also, pull down the File menu and select "Page Setup...". Make sure everything looks find and click OK. Then, go to Print and click Preview. Make sure this looks correct before printing. Then try printing again.
If you still have a problem, you may have a corrupt system font (or fonts). This may also be a cause for your second problem. Either a corrupt font, or a specific font isn't present, so it tries to substitute.
Thanks for the quick reply.
Correction on the second case. Its Windows only, one layout only.
I'll check what you've suggested.
WHY have these symptoms only appeared after FM10 was installed. Is FM10 more particular about printer drivers and fonts than FM9?
Is this a warning/note that should be included in FM10 install instructions?
I don't know why these symptoms only appeared after FileMaker Pro 10 was installed. Several people in Technical Support shrug their shoulders. No new printer problems for FileMaker Pro 10 have been reported, so it may just be coincidence on this one machine. Sorry I can't be more definitive.
