It’s weird about doing this on a Mac without any special program.
I wrote this! 🙂
Long story short:
I only like to print from Preview.app and it does not do tile printing. (?)
Regardless that there are already many ways to do this, like with Acrobat Reader, I’ve decided to make my own online app to slice images for razor printing.
That’s where you slice/razor all the paper away and concatenate the inkjet prints into one big poster.
Just print “scale to paper” from Preview.app
