I had my perfect printer. It was a Lexmark 4037/5E. All the imaging stuff, including toner, was in a cartridge that lasted me about two or three years (I was doing a lot of printing then — about 100 pages a week). The cartridge was about $90, it had a straight paper path and had a setting for envelopes. That’s all it did. It was wonderful! Lasted about 18 years, then I had to finally get rid of it because there were no longer drivers for it. It became incompatible with everything. I nearly cried when I sent it for recycling.
