Should I buy an inkjet printer or a laser printer?

I'd really look into this closely before you buy anything. with 200 pages a month, the math isn't as straightforward as a lot of people think. inkjet printers do have lower upfront costs, but the ink cartridges are ridiculously expensive and often don't last as long as they claim. what's really annoying is the ink drying out when you don't print for a while - and in a home office that happens pretty quick. i looked at a ton of reviews on this and loads of people complain about exactly that. with lasers you pay more upfront (usually 150-400€) but the toner cost per page is way cheaper and lasts forever. plus you don't have problems with dried-out nozzles.

for your volume i'd say: laser makes sense. roughly calculate 2-3 cents per page with ink versus 0.5-1 cent with laser, if you factor everything in. over a year that's 2400 pages and it's already a real difference. on top of that laser printers are just more reliable and you don't get constant hassle with nozzle cleaning. i'm skeptical about this stuff and looked at several test series beforehand - the result was clear cut.

a smaller laser printer in monochrome (black and white) does the job perfectly fine for letters and invoices and doesn't cost the earth. if you later realize you actually need color more often you can always switch later. my tip: don't just look at the upfront costs but calculate it over 3-5 years. the picture becomes clearer then.
