The **HP LaserJet 1020** is a low-cost, low-volume, monochrome laser printer released in June 2005 as a replacement for the HP LaserJet 1012. It prints black and white pages at up to 14 pages per minute, has a 234 MHz processor, 2 MB of RAM, and connects via USB 2.0. Its monthly duty cycle is rated for up to 8,000 single-sided pages, with an average usage of around 1,000 pages per month. It uses the HP Q2612A black toner cartridge, which has a standard capacity of about 2,000 pages at 5% coverage. This printer has been discontinued by HP, but compatible toner cartridges are still available from third-party suppliers[1][2][3].

Additional details:
– It exposes only the ZjStream protocol externally.
– The printer was found to be a moderate emitter of particulates, which was studied for potential health effects.
– HP no longer sells or supports the printer directly, but supplies can be found from aftermarket providers.
