I have had a huge amount of probs printing with VW11.5 and Acrobat Pro 7. I have had a number of problems using normal 'Priint' and 'Batch Print' commands at differing times.
1. No save file dialogue appearing.
2. If this happened, then either;
-a PDF was created under a generic name on the desktop
-a print file was sent to the PDF Printer, but then the print jobs would stop and I would have to delete them to get the PDF printer going again. (Not that it would be much use in this state)
-no print file would be created
After reinstalling Acrobat a number of times, finally today it is back up and running. I un-installed Acrobat (using the un-installer in the Acrobat folder). Downloaded the full disc Image updates (not through the auto-update in the app - unfortunatley it was about 180Mb download all up!), restarted, installed Acrobat, and installed the apps.
All is going well. In the 'Batch Print' command, a save window now comes up for each sheet. All works dandy. Hope this helps, and I hope you have broadband internet! Cheers
