Normally,  you change it and it will remember it for the next time you come in at that workstation (at least in current versions it does).

That is for everything except STANDARD.

As Tom said it should remember the setting last used for that user on that workstation as long as you are using a form code other than the STANDARD form code. I do agree that you should be able to set a default for this but within the Sage system the only was I know of is to make that user print with the desired settings once and they should stick.

The fact that Sage then remembers the settings makes me think that somewhere out there these settings are stored and could hypothetically be set, a registry key perhaps? Does anyone out there know where these settings are stored and if they can be manually modified?

For check printing the default form is set in Bank Code Maintenance.
