PRINTERS
Given the amount of documentation created
in business, a printer is the most necessary
piece of equipment needed next to the
computer.
 The most common printers today are laser
printers, inkjet printers and dot-matrix
printers.
a. Laser printers- offers the fastest, most
efficient way to produce text and images,
offering high speed and good resolution at
relatively low cost.
b. Inkjet printers- use tiny jets to spray
droplets of ink onto the page, and the
refinement in the ink compound has made
this technology attractive and highly
affordable.

◦ c. Dot-matrix printers- are impact printers

single pass, allowing them to produce
more pages than even high-speed laser
printers.
Choosing a Printer
◦ Printers are pretty much a commodity product, so
pricing is very competitive among the major
brands.
◦ following points are to be considered before
choosing a printer:

1. Printing speed. This is the no. of pages the
printers can print out per minute. Speed is determined by
the processor in the
printer: high-speed printers cost
more.
2. Paper tray capacity. A capacity of up to 250
pages in one tray is adequate for some and not for others.
Some printers offer more than one tray, which is a valuable
feature, if you switch from plain paper to letterhead, and
also handle envelopes and documents with the same
printer.
3. Black-and-white versus color. Graphic artists
and people involve in marketing communications probably
have a regular need for color printing.
SCANNER
◦ Is a device that can read text and graphics. A
copy of the scanned image is stored on
magnetic media as it simultaneously
reproduces on a monitor.
◦ Accuracy depends on the quality of document
being scanned, so the smart user should
review the scanned image for the occasional
error resulting from the scanner misreading
data.
◦ Most scanners come bundled with Optical
Character Recognition(OCR) capability that
can convert images into computer editable
format. Scanners are available at affordable
prices for every level of user.
UNINTERRUPTIBLE
POWER SUPPLIES
