I'd actually say to anyone in a similar situation, if you can keep finding really good deals, offloading the printer and buying a new one would be a good way to go for infrequent printing. Resell/donate the old one to somewhat reduce waste and lower the effective cost of the replacement. Though this does kinda hinge around finding deals, seeing as how new printers have "starter" cartridges (as others have alluded).
I used to have a nice color Ricoh color laser -- clear toner cartridges that were seperate from the transfer rollers so it was like a giant inkjet cartridge. Just unchipped and you could refill by simply sliding open a little access door. It was great till one of the transfer rollers started to go out, and I then broke the fuser paper guides. The fuser alone costs more than the printer did when I purchased it, and the transfer roller cost more than a new Brother mono laser (and there's 5 in the printer). So we got a Brother monochrome laser.
We currently get refills from Lasertech (or is it lazertech, I forget). You can buy bulk pack refill kits and normally get percentage or dollar-off coupons, so I think we usually pay $40-$50 for three refills. Each refill is good for about 3k pages at 5%, though we often do 20-70% coverage prints.
I must be the only one who still prints something every single day.
Nope. If we don't print every single day, we at least print very frequently. My girlfriend is a kindergarten teacher and the school doesn't supply enough paper, copier toner, or ink for her inkjet, so she has to print out a lot at home. I just ran a stats page on my Brother printer, and we've churned out 7100 single sided pages and 2400 duplexed pages in the past 9 months. We have an Epson AIO inkjet with 8 ink tanks which my girlfriend prints color singles to do color copies later (as we no longer have a color laser), but I'm not sure on its consumption.
