I suspect they went with something like that because the infrastructure was there for them to start with (creating a standalone file for sneakernet, people are used to the idea of a print to PDF file option, and they may have used the existing code to start from). But I can't imagine why they didn't just go with standard PDF files, perhaps some Adobe fees they didn't want to pay. I recall years ago one of the print to file options in programs being print to a PostScript file. I don't see that any more. -- uname -rsvp Linux 3.10.0-1160.66.1.el7.x86_64 #1 SMP Wed May 18 16:02:34 UTC 2022 x86_64 Boilerplate: All unexpected mail to my mailbox is automatically deleted.
