Inconsistent page setup on different printers

[brianrich]

I have a multi-user Filemaker system (Mac OS9) where two different types of printer are used, Epson 760 and HP deskjet 843C.

I have set up separate scripts that perform page setup for landscape and portrait modes, making sure that the page setup information is stored by 'replacing' the page setup information. The problem is that if I set these on the Mac with the HP printer attached, they work OK, but won't then work on the 760, where both scripts result in a portrait orientation. If I 'replace' the page setup in each script on a Mac with the EPSON 760 attached, the page orientation then doesn't change on the HP Deskjet if I run the different scripts.

Is this a printer driver problem, or do I misunderstand how this feature works?
