It is easy to feel
overwhelmed by the large number of printer models that are available.
This month we look at the two main types of printers (inkjet and laser)
and what to consider when making your purchasing decision.
Inkjet Printers:
Inkjet (or
bubble-jet) printers squirt tiny dots of quick-drying ink onto your
paper, one line at a time. All 300-600 jets can fire simultaneously and
each dot is tinier than the width of a human hair. Inkjet printers are
usually less expensive than laser printers, due to less expensive,
fewer mechanical parts.
If you are printing graphics, it will use considerably more ink per page
than printing text, and ink is more expensive than toner in a laser
printer. Also,
printed
characters generally do not appear as crisp and sharp as those produced
from a laser printer, so consider what level of quality you require for
your finished documents.
Laser Printers:
Laser printers take
advantage of a drum coated with a static electricity charge.
A laser “writes” to the
drum by changing the static charge where it touches leaving an
electrically charged impression of your document on the drum. As the
drum turns, toner sticks to the electrically charged parts of the drum.
Then, your paper is fed into the printer and charged with a different
electrical charge than the drum, so that when it passes by the drum the
toner jumps to the paper, transferring your image. It’s
like writing with glue then sprinkling sand on top. Finally, the paper
passes through heated rollers which fuse the powder to your page,
leaving you with a dry, warm and smudge-free document. And whilst laser
printers may have a more expensive initial purchase price, their
long-term ‘cost per page’ is less.
Ink tanks / toner cartridges:
Laser printers
usually have black, yellow, cyan and magenta toner powder cartridges. |
Inkjet printers can
vary between 2 ink tanks (1 x black and 1 x combined yellow, cyan &
magenta) and 8 separate tanks (matte black, photo black, cyan, magenta,
yellow, light grey, light cyan & light magenta). With a combined ink
tank, if you run out of yellow, you need to replace the whole tank
regardless of how much magenta or cyan you have left. With separate
tanks, you would just replace the yellow one.
Speed
As paper passes a
laser’s drum at speed, the average laser printer can deliver around 26
printed pages per minute.
Inkjets must work one
line at a time (around 4 pages per minute), so
large volumes of documents will take much longer to print on an inkjet.
This might not be a problem if you are printing a few
letters at home, but if you are running a busy office then printer speed
may be a consideration.
Duplex and paper trays
Some laser printers
come with optional extras, like duplex units (for double-sided printing)
and additional paper trays (e.g. for your company letterhead paper or
envelopes). A duplex feature can literally reduce your ongoing paper
costs by up to half.
Multi-Function
Multi-function units
can offer features like printing, scanning, copying & faxing all from
the one device. This can save you a lot of space. However, consider
that if a function like the scanner breaks and needs to be repaired, you
may also be without your printer, copier and fax whilst the unit is with
the repairer.
Talk to your local
Computer Troubleshooter about what they would recommend for your
specific printing needs.
