The HP LaserJet 1020 is an inexpensive ($180) monochrome laser printer which is best suited for home users with low to moderate print needs. The compact LaserJet 1020 measures just 14.6 inches wide, 9.5 inches deep, and 8.2 inches tall, and weighs a light 11 pounds. This monochrome laser printer comes with a 234MHz processor and just 2MB of onboard memory. It has just a USB connection, so it’s better for single users than a multi-user environment. This cheap printer also contains 150 sheet input tray and a single sheet manual input tray. The output tray includes the fold out paper support.
The LaserJet 1020 is a mono printer and therefore contains only one toner cartridge. Replacement cartridges cost $70 and are good for up to about 2,000 prints, which come out to about 3.5 cents per page–not bad for a budget laser printer and in line with the Samsung ML-2571N’s 2.6 cents per page and the Lexmark E250d’s 3.8 cents per page. The recommended monthly duty cycle is 5,000 prints, so the LaserJet 1020 is best suited for home users with home users with light printing needs.
The HP LaserJet 1020′s speed and quality are not the best among its competition, but not terrible, either. It printed text at a rate of 12.52ppm (pages per minute) and graphics at a rate of 12.61ppm. The text quality of LaserJet 1020 is also excellent.
