How do I know if I need a LaserJet printer?
HP Laserjet printers are workhorses designed for the long
haul - that is, they can turn out a high volume of pages
per month. So, if you are looking for a personal desktop
or a shared office workhorse, an HP LaserJet may be the
best option. Another factor of importance to both the home
and business user is the handling of envelopes, cardstock
and other non-traditional media, where Laserjets are
perfect for any size job.
What are the key considerations in choosing a LaserJet
printer?
Resolution: The standard resolution in most laser
printers today is 1200 dots-per-inch (dpi). This
resolution is well suited for normal everyday printing
including small desktop publishing jobs. A high-end
production printer might have a resolution of 2400 dpi.
Some laser printers still use a resolution of 300 dpi.
This resolution can cause jagged lines to appear on the
outer edge of an image. Hewlett Packard created RET
(Resolution Enhancement Technology) to correct this. RET
inserts smaller dots at the edges of lines and to smooth
the rough edges. RET does not improve the resolution, but
the document looks better. If you purchase a printer with
300 dpi, make sure it has RET.
Printer languages: Printer Control Language (PCL)
is the standard printer language for Hewlett Packard and
most other laser printers (which are mostly
HP-compatible). PCL is used for printing letters, database
printouts, spreadsheets, and simple graphics. Postscript
printers or printers that can emulate postscript are used
with desktop publishing software and drawing packages.
Postscript capable printers are the norm for Apple
Macintosh printers. A laser printer that uses PCL can be
upgraded to Postscript by installing a software driver
provided by the manufacturer of the laser printer. The
printer might require more memory when upgraded to use
Postscript. This is because a laser printer needs the
entire image in memory before printing, and a Postscript
printer requires more memory to process than a PCL printer
does. The application being used must support Postscript
in order for the laser printer to print Postscript
documents.
Paper handling: Paper handling is important when
shopping for a laser printer. Most laser printers use
letter-size, cut-sheet paper. Additional paper trays or
feeders can be added to increase the capacity or variety
of media. High-end production printers use continuous
sheet paper. Laser printers can print on a variety of
papers sizes, types and weights such as transparencies,
adhesive labels, and card stock. A laser printer with
duplex printing can print on one side of the paper, turn
the paper over, and print on the other side. Most laser
printers, however, use simple printing with manual duplex
printing. Manual duplex printing is achieved by changing
the print options in the printer's properties or printing
one side and taking that same paper and reinserting it
into the printer to print on the other side.
Memory: Most LaserJet printers come equipped with
enough memory to meet the needs of normal printing or
sharing of a printer over a network. It is important to
select a LaserJet printer that allows for easy expansion
of the printer's memory so you can adapt to changing
printing environments.
FPOT (first paper out time) and warm-up time:
A final consideration in purchasing a printer is FPOT and
warm-up time. When a laser printer receives data from the
computer to print, it takes 5 to 30 seconds to prepare the
printer to print a new job. This is in addition to the
time it takes to actually print the document. The warm-up
time is important. When the printer is turned on, it needs
time to warm up the fuser to operating temperature. If the
printer has a standby mode or is turned off between
printing jobs, the warm-up time becomes even more
important. LaserJet printers that have "instant
on" fusers are designed to reduce FPOT.
