TAG and TAG2 contain p-code (semi compiled code) of what's in Expr.

The main problem is that your report overwrites the settings at run time. If you are like me, and you include the reports in the project (.PJX) then the report overwrites the current settings. The only control you have is to use the prompt clause of the report.

... or empty out Expr, Tag and Tag2 at compile time and set the printer at runtime like you suggest. You can do that by hacking the report (.frx) file just before you build your app.

HTH and that it's not to late.

Uw buur.
