That's all right: then you were only confusing half of OS users and some 
pythonista, NOW you're upsetting HALF the WORLD!

"Spring"??? That's what it is right now in the southern hemisphere, but 
was six months ago in the northern (and is practically unknown by those 
living 'in the middle').

See earlier comments about "OS level". Are you able to print from other 
s/w under Ubuntu? (even the printer's Test Page)

Modern Linux-es prefer to run printers through cups, and HP require an 
extra apt-get to receive the facilities to drive/monitor printers (and 
scanners, if appropriate).
(?hpijs - Fedora's s/w name(s) may be different to Ubuntu/Debian's)


Insert obligatory comment here - Python 2.n becomes 'end of life' in 
less than 50-days!
(not that this appears to be a Py2/3 issue)
