When you output PDF, you are using different "printer drivers" than when you print to a specific printer.
Be sure you have the latest printer drivers installed for your printer model, and that the page setup has specified your printer model.
If you still have a printer problme, try printing to a different printer to see if this is an FM problem of an FM-printer compatability problem.
Provide info on the printer model/version that exhibits this problem, and the specific rev of FM11. Lots of know printer compatability issues have been documented for FMP over the years. The devil's in the details.
Thanks for the reply, Stephen. The solution was to reset the "Print Setup" and "Print" script steps (delete them from the script, select the steps again).
