Why is macOS system printing quicker than Chrome or lpr?

Viewed 364

I noticed that printing the exact same pdf file to the exact same printer does not always take the same amount of time:

  • Printing from macOS preview's default printing dialog is very fast.
  • Printing from Chrome browser's built-in print dialog is slower. The printer pauses for a moment after starting the print job.
  • Printing from the command line with lpr has the same effect as printing from Chrome's built-in print dialog.
  • However, switching to the system printing dialog withing Chrome makes things fast again.

My goal is to make printing from the command line with lpr as smooth as from the system's dialog. What could actually make the difference?

lpr -o landscape /path/to/my/file.pdf is my current command. The generated output is as expected, just too slow.
