Simple problem, but I was not able to find a solution on my own...
All day long I am printing either 8.5" x 11" PDF reports or 3" x 4" PDF labels.
If the PDF page size is 8.5" x 11" I'd like the default printer set to my inkjet printer.
If the PDF page size is 3" x 4" I'd like the default printer to be my thermal label printer.
I am using Acrobat Reader now and can't find any settings that would allow this. I am open to using any PDF reader that has this functionality.
