This has been discussed quite a few times ad nauseum on these lists. To find your most likely fix, go to <http://www.adobe.com/support/techdocs/1a816.htm> and follow its directions. This also applies to AdobePS versions greater than 4.2.6. (I'll almost bet that you are creating PDF files from the PostScript driver configured for the LaserJet 4 instead of using the Distiller Assistant.) - Dov At 11/30/2000 05:51 PM, Michael Cudmore wrote: >System info: >------------ >Windows 95 OSR2 or 98 SE >FrameMaker 5.5 for Windows >AdobePS 4.1 >Acrobat 3.01RA with Distiller upgraded to 3.02 >HP LaserJet 4 with postscript kit (6 MB) > >The situation: >-------- >Testing the AdobePS 4.2.6 driver, with a view to upgrading from the >4.1 version. > >The problem: >------------ >When I change printer drivers from 4.1 to 4.2.6, the positioning of >some elements in FrameMaker's equations changes quite dramatically. >With the 4.2.6 driver installed using the same PPD, and using the same >fonts in the same FM document, some of the equation elements, such as >superior/inferior tilde and arrow (i.e. vector notation) are spaced a >lot further from the normal position text than they were with the 4.1 >driver.
