I made a network printing app... https://github.com/attah/harbour-seaprint
I'll refrain from getting in to the "Why not CUPS discussion" as an intro, but it was considered. All it does is IPP (Internet Printing Protocol) and sending the raw PDFs (or JPEGs) over to the printer.

One of the goals with this, and SFOS Devember in general, was to make Sailfish OS more feature complete and as such more approachable for the average person. So it is deliberately harbour friendly. Personally printing barely a blip on the nice-to-have radar, so hopefully i can get it to a state where maintenance is low, and perhaps a few contributors will show up.
At least it was a fun challenge.

TJC is pretty limited for discussions, so i'm trying here for improvement suggestions and discussions on future features.

Please do share experiences and wishes.
