I can go months between needing to print, maybe even over a year. It is infrequent enough that the Brother laser printer I bought a little over 7 years is still on the toner cartridge that came with it and has maybe 1/4th or 1/5th left and still works perfectly.

Before that I had several inkjet printers (one I bought, and at least 3 that came bundled when I bought computers), and on every one I got maybe 5 pages per cartridge.

One particularly annoying time I went to print and the cartridge was dried out, I bought a new cartridge which the store only had in a two pack, and printed what I needed to print. Next time I needed to print that cartridge was dead, and the unopened one I had bought at the same was also dead.
