Switch to Another Printer in Script WITHOUT Printing

[PaulHunt]

I have a script (and button) to print a label on my label printer. The script switches to the appropriate layout, does a Print Setup, prints to my label printer, then switches back to the original layout. Works flawlessly.

But I then want to switch my chosen printer back to my letter-size printer WITHOUT PRINTING ANYTHING. I can do a Print Setup, but how do I also set my letter printer as my chosen printer? I don't want to inadvertently print my next FM document to my label printer. None of this needs to be dynamic, just hard-wired into the script.

Thanks,
Paul
