I can't be the only one experiencing this but I didn't get any luck in a search.

I don't sell that much but when I do I generally just buy and print a postage label through eBay. No matter what browser I use, the label appears in the top left quarter of an A4 PDF, making it smaller than A6 including margins.  The text is so small it is barely readable. I cannot resize it in any way during printing, it seems to be locked to that size.

I actually have to save the PDF then enlarge it in photoshop to get it to print out closer to A5 in size. I've tried different browsers and different printers. What am I doing wrong?!
