Inkjets use several different technologies for spraying the ink onto
paper. Some of them rely on electrostatic charge in the ink itself,
and use a counter charge to force the ink out the nozzles. I'm not
sure that that means those printers using different inkjet technologies
are actually faster to warm up, but I assume that's the meaning of the
message on Karl's printer(s).

But inkjets also often get drop-out or fade-out lines when one or more
nozzles are clogged. When this happens, the acceptability of the
printout is also a bit subjective. I find inkjets suffer this problem
on a more frequent, but also a more intermittent, basis than lasers do.

That is, with lasers, once the banding starts, that's it for the toner
cartridge. You can get slightly more life by shaking the cartridge,
but basically it just gets worse. Inkjets, on the other hand, can have
problems even with a nearly full cartridge; you can usually make it
better with one or more cleaning cylces, but the fix is erratic.
