Hi :)

I am not sure I really know how to apply a printer profile using it.
In the Options -> Colour Management dialog, simply set the Printer Profile to the profile you've made for your printer, and set the Default RGB profile to sRGB or whatever you prefer. Images will now be transformed into the printer's colour space when printing. 

PhotoPrint could definitely use some decent documentation!


But what would photoprint do with an 8 bit per channel image that
cctiff, for example, wouldn't do.
Nothing really - you just avoid losing a small amount of colour information by quantizing to 8-bits again after applying your printer profile. PhotoPrint keeps the data in 16-bit depth from the output of the colour transformation right through to the driver. How much that matters depends a lot on how well-behaved your printer is, and thus how well your printer profile makes use of the 256 codes available in 8-bit data. 

All the best,
