If you seriously want to print the patterns as they are, you can select the entire order list, copy it and paste it into a text editor to print it from there.

If you want to print sheet music, there is a FAQ entry for that: https://wiki.openmpt.org/Manual:_Frequently_Asked_Questions#I_want_a_score_of_my_module_music

PS: Please always create one issue per feature request.

Okay, I will create another feature request for the colors, although it also brushes the printing option.
Your suggestion (copy-pasting) I will try, thank you!
