Am writing a project hook to clear out the junk from EXPR fields on FRX tables. Below is a sample of the contents of EXPR. I know i need to keep ORIENTATION around, or my landscaped reports get printed in portrait mode. What else do i need to keep and what can i delete? Anything else that is NOT in the example below that i need to look out for?

DRIVER=winspool
DEVICE=\\ame-server2\Jet1
OUTPUT=IP_10.10.0.201
ORIENTATION=1
PAPERSIZE=1
SCALE=100
ASCII=100
COPIES=1
DEFAULTSOURCE=7
PRINTQUALITY=600
