I've been modifying a report today and selecting different printers and then different trays for each of the printers and recording the settings for those printers into my help file. I have found some patterns to the DEFAULTSOURCE but then some really add values as well. I'm not done yet so I can't report anything conclusively. But I edit the Report change the printer settings and then save it and then open the EXPR field and record values. It's a little slow and tedious. I'm in the middle of another project so I haven't had all my time to it today!
