Well the labels are already in PDF format from the USPS site. BUT... of course its going to be the newest/latest/greatest PDF format there is, which will likely not open in Acrobat 3. 

However, that leads me into another tangent: I took a splurge and picked up a modern"ish" laser printer cheap on ebay. Laserjet 1012.

It is USB only so no network, or anything. I can attach it directly to my PC.

That brings up the question: Is it possible to printer modern printers from vintage macintosh machines? Just curious. I am sure I would have to share the

printer as a windows share, but from that point forward, I dont know.

any ideas?
