Rather than an entry-level laser printer that cannot be economically repaired, a used mid-level enterprise printer is often the cheapest option long term and saves useful electronics from becoming e-waste. Office furniture rental/repo places and secondary markets like eBay have these.
In large enterprises, a printer's cost per page tends to be inversely proportional to (increased) initial acquisition cost and availability of repair parts. Put another way, giving everyone an entry-level printer would be far more expensive in acquisition costs, per-page costs, and an inability to repair them. (hitting TCO 3 ways).
I had a HP LaserJet 4 (released 1992, purchased new ~1994) until 2013 with a used JetDirect card. It had expansion options with cartridges and SIMM RAM and font options, but they weren't strictly needed.
