What is the difference between an office jet printer and a laser jet printer?
An Inkjet printer uses a printhead to "shoot" ink on to a page.
An electronic device actually boils the ink, making it expand and
shoot out. You can get some more information at the related link
below.
Most laser printers use toner, which is a powder made of plastic
and a little metal. A laser writes a picture onto a drum: whereever
the laser writes attracts toner. Then the toner is transferred to
the paper and melted in to the paper. You can look up more of this
process at the other related link below.
The bottom line is inkjets have a better print quality, although
most are slower and can't be repaired if they break. Laser printers
are made to print thousands, if not millions of pages in their
lifetime. Laser printers are more expensive than inkjets but you
will spend more on ink cartridges than toner cartridges over time,
depending on how much you print.
