Types of Printers
Printers fall into two categories:
 Impact printers use a device to strike an
inked ribbon, pressing ink from the ribbon
onto the paper.
 Non-impact printers use different methods
to place ink (or another substance) on the
page.

Dot matrix printer – Dot-matrix printers
were once very popular, but have been
replaced in popularity by ink-jet p5rinters.
Dot-matrix printers typically use continuous
form multipart paper and are commonly
used for documents such as sales invoices
and purchase orders.
Inside a dot-matrix printer a print head
containing small blunt pins strikes an inked
ribbon to stamp images on a page.

Ink-jet Printer – An ink-jet printer produces
high-quality documents at a relatively low
price. You can use the documents
produced by an ink-jet printer in most
circumstances, except when only the
highest quality is acceptable, such as for
important business correspondence.
An ink-jet printer sprays ink through small
nozzles onto a page to produce images.

Laser Printer – A laser printer is a high-speed
printer that is ideal for business documents and
graphics. Laser printers produce the highest
quality images, but are relatively expensive.
A laser printer works like a photocopier to
produce images on a page. A laser beam draws
images on a light-sensitive drum. The drum picks
up a fine powdered ink called toner, and then
transfers the toner to the paper to create the
images.
Laser printers produce higher-quality print than
ink jet printers, but are more expensive.

series of beeps to alert you or display a
message that tell you a problem has
occurred.
Paper jams are the most common type of
printer problem. Most printers have panels
that can be opened to check the paper jam.
