Someone remarked that something I did the other way was genius. I’ll concede that it was mildly clever, I’ll let you decide.
I took something off someone’s hands in the LowEnd Mac swap meet (a mailing list where people horse trade stuff for old Macs, some not so old), and to save hassle on both ends, I created a postage paid mailing label at the USPS website, previewed it so I could save it as a PDF, and emailed that as an attachment. All he had to do was print and stick . . . .
Unexpectedly, the java applet that makes this work was fine in Safari but not in FireFox . . . so I could create the labels, just not render them.
