Hardware description
The HP LaserJet 1010 printer provides 600 x 600 dpi printing. The HP LaserJet 1012, 1015, and 1020
printers offer HP REt technology for 600 x 600 x 2 dpi printing (effectively 1200 dpi).
The printers print at 12 ppm (HP LaserJet 1010) or 15 ppm for letter-size paper and 14 ppm for A4-size
paper (HP LaserJet 1012, 1015, and 1020). With 600 dpi printing for the HP LaserJet 1010 printer and
an effective 1200 dpi printing resolution for the other models, the printers have exceptional text and
graphics print quality. The simple control panels and improved paper-handling make these printers easy
to use.
The main input tray has a 150-sheet (75-g/m
2
[20-lb] media) capacity for continuous, multiple-page
printing. The priority feed slot is used to manually feed single sheets of most recommended media and
holds up to ten sheets of 75-g/m
2
(20-lb) media. Both the main input tray and the priority feed slot are
center-justified for all supported media sizes. The output bin holds up to 125 sheets of 75-g/m
2
(20-lb)
media.
These printers have a very fast first-page-out, at less than 10 seconds to first page out. The base memory
contains 8 MB of RAM for the HP LaserJet 1010 series printers and 2 MB for the HP LaserJet 1020
printer. These printers use an embedded 133 MHz processor.
The print engine has an average duty cycle of 1,000 pages per month (7,000 peak) or 50,000 total pages
printed. The standard print-cartridge life is 2,000 pages, in accordance with ISO/IEC 19752.
NOTE Actual print cartridge life depends on specific usage.
