Broadback used his keyboard to write :
I have a HP Photosmart 7520 printer. It gets intermittent use, the problem is
it needs sorting almost every time I wish to use it. The cartridges dry, or
some other problem develops. I suspect it is not happy with spending quite
long periods of time idle. I am seriously considering getting a laser
printer, are these as liable to problems through inactivity? If not would
someone care to make a recommendation? I would like colour but an associated
scanner is not necessary. TIA

Laser printers can just sit unused for month years, they cannot dry up
like an inkjet. They use a superfine 'plastic' dust, which is set on
the paper by heated rollers.

You can now get cheap colour desktop lasers for not a lot, or there are
plenty of more capable office lasers given away on the likes of
freegle, when offices upgrade - especialy B&W ones.

I have an old ex-office HP4000N with all of the accessories, including
duplexer so it can print both sides. I have had it 10 or 15 years and
it has given me problem free service all of that time.
