Well. Parts of hplip are in python; and hplip then uses:

	import platform
	dist = platform.dist()

platform.dist() will try to guess the Linux distro from /etc/lsb-release 
(should not exist), then /etc/*-{release,version}, hence /etc/os-release.

hplip uses its own internal list of supported distros, in
	/usr/share/hplip/installer/distros.dat
… shipped from hplip-data.

It only gained "Buster" support in 3.19.8; so could any of you try to install 
distros.dat from 
https://salsa.debian.org/printing-team/hplip/raw/debian/3.19.8+dfsg0-3/
installer/distros.dat 

into /usr/share/hplip/installer/distros.dat, and try printing again?

(That is:
	wget -q 'https://salsa.debian.org/printing-team/hplip/raw/debian/
3.19.8+dfsg0-3/installer/distros.dat' -O - | sudo tee /usr/share/hplip/
installer/distros.dat

)

I'm not sure it will work, as printer-driver-hpcups doesn't depend on hplip-
data anyway; *sigh*.

(It seems this whole "detect the distro and try being smart" should be removed 
completely from Debian's hplip).

Cheers,
