Yup... I get that it's not so much an attitude as an inescapable thing that's being forced on us by the printer manufacturers. Makes me wonder if it wouldn't be worthwhile to develop a more sustainability-conscious line of printers or printer modifications? Just a thought...They have those, too. But the price of the printers is much, much higher. I've seen some as high as $15,000 US. And others as low as $1,000 US. While all they do is print monochrome on letter size - they may be fairly fast (50-100 ppm?) but, still.
Might want to have a look at Okidata's B4250 LED printer? Toner cartridge is designed to be refillable (refills are about ten bucks apiece at Office Depot) last for about 2500 pages, new cartridges are $40.00 US, (and that's OEM consumables, not some knock-off) and it has a CUPS driver available for download at Okidata's website. Page printing speed is about 10-11 ppm. (I remember printing to this printer just fine from PCLinuxOS 2007...)
We had a bunch of these at work a couple years back, and they've all been replaced by networked muti-function devices. Many of the old B4250s have been pressed back into service at remote locations and are still kicking out things like alarm log pages. Impressive little beasties. (They don't take to gettin' wet all that well, but what printer does?)
I see where the B4250 may have been discontinued? The B4600 is now selling on Newegg.com, and is the replacement for the B4200 series. It looks to be a bit more expensive, but still has the same separate toner and drum design that makes for inexpensive operation, a much higher page printing speed (advertised at 27 ppm!) and one reviewer says it still works well with Linux and windows. The B4600n is the networked version, for those interested in such things. The base model without networking goes for about $286 US.
