For those not in the know… PDF is a particular set of conventions for delivering peograms written in a programming language called “Postscript”, and like all programs they can be hijacked to trigger unexpected results, including the delivery of software viruses. And yes, while those programs run in “sandboxes” that are supposed to prevent propagation of harm, such environments can fall in that purpose due to creative triggering of imperfections in the sandbox code by the “contained” Postscript code.
Hence, quotes are used to convey lack of trust in the claim of safety.
Next time someone asks me what PDF stands for, this is what I will tell them
(I’m reflecting on how many times I’ve been asked what PDF stands for, because my comment would suggest it is a thing that happens often.

I think I’m just most people’s token techy friend. Or more specifically, I’m the techy friend who also knows loads of random shit and really enjoys answering random questions)
Yeah, if you print to a printer what you’re most often doing is saving it as an Adobe PostScript file and sending that to the printer. PDF is similar, just with extra bells and whistles.
It was like that back in the eighties, until the manufacturers decided to save on the chips by moving functionality into the drivers. Which was basically the start of everyone’s problems with printers.
Im not so sure. I bet more than half of the drivers out there produce PCL output, and there are a lot of printers that use other languages too like ZPL and a myriad of others.
Until you realize that a PDF is literally just a format based around a standard set of instructions used to print documents.
It stands for Print Da File.
Reminds me of Arnold’s guide to tar:
Print Deeznuts Fuckyou
Potable Document Format. Retains formatting and safe to consume.
“safe”
Why is my PDF file booting the Linux kernel?

Apple‘s AirPrint standard for wireless printing is pretty much sending a PDF over IPP.

To be fair, they added stuff to it, like selectable text on a scanned page.
Right, as another user said, it’s similar to postscript but with bells and whistles.
