We had a printer-scanner some years ago and it would stop functioning unless all the ink cartridges were branded and full.
Isn't that illegal under competition law - that you don't get free choice as to which ink to buy? Or would they just program them that way and then deny everything?
I work from home as the main admin person, so I have a colour laser printer/scanner at home provided by work, who also buy all of the supplies. 99% of what I print is for work, but it's handy having it for the odd bit of our own printing well, we pay for the electricity anyway.
It's a Canon, which I've certainly found much less annoying than the previous makes I've had - HP and Epson being especially bad. It does warn you to beware of the ubiquity of 'counterfeit' ink, by which I suppose they technically mean fake ink pretending to be official Canon ink, but is obviously designed to make you panic about using third-party compatibles that never claim to be the branded stuff too.
However tempting it is, ever buy a printer for less than £100-£200. They're designed to fail and are treated by the manufacturers as effectively just the packaging for their expensive inks.
I would definitely never go back to inkjet again. I would have used the word 'diva' too! You're relying on every single one of the many nozzles staying clean, clear and functional, which they inevitably fail to do after a while - just one of them out will likely nobble your whole page. It's such frustrating, fallible technology.
I don't know the scientific details of the exact workings, but lasers give a much better and reliable coverage and finish. Inkjets are designed to be extremely fancy in their design and spec; lasers are just designed to get the job reliably done. Lasers will last you for far, far more pages, over a good few years, and when they eventually die, they're well and truly borked and it's time for a replacement. Before too long, with an inkjet, you just have to get used to it getting less and less good and putting up with it until it eventually just gets too bad and irritating to tolerate any more.
On an entirely unrelated note, it so happens that inkjet printers were invented by a man whereas laser printers were invented by a woman....
