Xournal allows me to fill out anything I could print from PDF with a stylus on my touch screen. If I want to read and highlight something, I convert it to PDF and read it in Logseq with the same stylus. I can highlight in four colors and it automatically collects my notes!
If I need to mail/ship something, I just have the ship shop print it.
What are people intentionally printing to paper for, often enough that it's worth having a printer?
