Our documents are intended to be printed on a pre-printed form that our printer has set up as different paper medium. Forgetting to chose that is obviously rather annoying, but changing the printer's default medium would just invert the problem for the equally present non-form printouts.
In order to alleviate this, is there any way to have the PDF contain information on the required (or preferred) paper medium (in addition to the unchanged size)?
edit It seems at least in PostScript3, there exists Page Device Parameters which apparently can be used to achieve this, but as of yet I don't have a clue how to do this and whether this can be used in PDF as well. But I'm not stuck with PDF, hints on how to obtain a PS file using this via InDesign are as well welcome.
