This is about to become amusingly confusing, because I'm in turn 
not sure what ‘it[0]’ refers to above.

If you mean the ‘[0]’: there was a link at the bottom of my mail 
to the PPD I tried.

If you mean the file itself: it's what this form[1] (another link 
below :-) produces from selecting your printer model and clicking 
‘Generate PPD file’.

I did not inspect how that site works, but as modern CUPS 
autogenerates .ppd files from .drv files, I expect it to do the 
same.

That's the binary-only (and hence unsupportable) .deb, right?

Wait, so it didn't work with the default list?  :-(

Also, was it not clear from the Guix manual that the default list 
should include all viable drivers?  If you have any suggestions to 
improve the wording, please let me know!

Great!  All's well that ends well.

I find it strange that the foomatic package doesn't offer you 
exact printer model when it probably supports it, but that's not 
really a Guix bug, I think.

Happy printing,
