Day 112: the old printer seems to be having print-head trouble, so time
to buy a new printer.
Of course the folks at the shop had no idea about Linux. Myself I would
have recommended an Epson or HP model, since I have first-hand
experience with those brands, but he wanted another Canon.
Took it home, unpacked it and plugged it in. Saw a message on the screen
that Linux Mint had detected a “Canon MG2500-series” printer. Went into
the CUPS printer-management screen; selected the newly-added printer,
tried printing a test page. It worked.
That was it. No need to go hunting for drivers or anything.
By the way, the printer, a Pixma MG2560, was $39.99 at Noel Leeming.
Replacement ink cartridges (of the “standard” capacity, same as those
that came with the printer) would have added up to over $70. Seems like
they would really rather you didn’t bother buying the ink, just get a
new printer when the ink runs out...
