Running following command works, but printer always prints really fast.

cat /Users/sunknudsen/Downloads/7663f4bd.pdf | lp -o media=4x6 -o print-quality=5

Printing same file using macOS print dialog and selecting “Best” quality results in slowing (and better) printing.

Is print-quality=5 equivalent to “Best”?

  • Not very familiar with the print dialog on macos but does it also use cups? If not it's probably a driver issue. I guess either way it's likely a driver issue. If you are using cups you have driver issues.

  • Thanks for helping out @jesse_b. macOS does use CUPS under the hood.

Found fix…

cat /Users/sunknudsen/Downloads/7663f4bd.pdf | lp -o MediaType=stationery-heavyweight -o PageSize=Custom.4x6in -o Quality=High

MediaType=stationery-heavyweight is what slows things down.
