#2This reminds me of that photocopier that changed the numbers it was copying sometimes, through a dodgy image compression algorithm.

#6Just in case you don't click through, the bug submitter refers to a color PDF (not a scan, so image compression artifacts are not an issue) that is similar in appearance to a periodic table. That is, it is not the sequence of `123456` that is mistranslated into `114447`, but a sequence of 6 table cells, each containing a single digit.
It's not just the numbers that are misprinted, but the text inside those cells too, which suggests that Edge's PDF engine is re-rendering the original PDF, rather than printing the original PDF as is, which I thought was the entire point of using PDF in the first place.
But maybe this is an edge case? In the sense that Microsoft assumes that given a PDF file, if a user wants to "Print to PDF", the user should just save the PDF file. "Print to PDF" is ostensibly used to convert HTML/DOC into PDF format.

Definitely an Edge case.

As someone who works in PDFs constantly (due to work in local government), I would say the point of a PDF is to be able to reproduce the result given a file, not to assume the file cannot be changed... you can easily edit and save PDF files using Acrobat, for example.
It is common that when you "print to PDF" you take the output of the printer and serialize that to PDF. I use this feature often on my Mac (which I think many would claim has excellent support for dealing with PDF files) to build a PDF that is stripped of any interactive forms: so as to get an output which is only the PDF "as printed".

Yes, note the tongue-in-cheek reference reference to that problem in the article:

#10Maybe we really should bring https://pdfviewer.io to Windows. Looks like the default app is somewhat crap :P
