Printers
Printing files and
documents can be as simple as clicking an application's Print
button. The hard part is deciding which printer is right for you.
This chapter defines printers, and explains the differences between
the most common printers available. In addition, you learn how to
connect a printer to your computer, and how to make sure it will
work with Windows 95.
Printers Defined
A printer is
the computer component that lets you create copies of the
information stored in your computer on paper. The printed material
is often called hard copy, to differentiate it from the data
stored on a disk, or held in the computer's memory.
There are three
basic types of printers available for use with personal computers:
|
Laser
printers. These
combine a magnetic roller with powdered ink called toner to
transfer high-quality characters or images onto a page.
|
|
Inkjet
printers. These
have small nozzles that actually spray fast-drying ink onto
the page to form characters or images.
|
|
Dot-matrix
printers. These use
a print head to strike an inked ribbon against paper, like a
typewriter, creating characters out of a series of dots. |
The type of printer
you choose depends on your budget and the type of output you need.
For example, if all you need to print are grocery lists, you may be
happy with a dot-matrix printer. In general, dot-matrix printers are
noisier, slower, and produce a poorer-quality image than do laser or
inkjet printers, but they are also less expensive. If you need to
print newsletters, brochures, or illustrated reports, you will
probably want a high-quality laser printer.
In general, there
are three main factors to consider when purchasing a printer:
|
Cost.
Printers are available ranging in price from a few hundred
dollars to a few thousand dollars, but the purchase price is
just the beginning. Paper, ink, toner, printer ribbons, and
the other consumables are required to keep the
printer running, and they all cost money.
|
|
Resolution.
Resolution is measured by how many dots per inch (dpi) the
printer can print. The more dots per inch, the higher the
resolution of the printed image. The higher the printer's
resolution, the better is its quality.
|
|
Speed.
Printer speed is rated by how many characters printers
output in a second (cps) or how many pages printers output
in a minute (ppm). The higher the number, the faster the
printer. |
Although the
primary considerations involved in selecting a printer are usually
cost, speed, and resolution, there are other issues that come into
play as well. Available fonts, the ability to print in color, and
the amount of maintenance involved may weight your decision:
|
Noise.
Impact printers such as dot-matrix printers are noisier than
non-impact printers such as laser or inkjet printers. If you
have a small or crowded office, noise can be an important
factor.
|
|
Software
support. PCs
communicate with printers using software programs called
printer drivers, and some printers come with built-in
printer languages, such as PostScript. Be sure that the
software programs you use support the printer driver and
printer language for the printer you purchase.
|
|
Fonts.
A font is the style of letters that your printer puts on
the paper. They are important if you want control over the
appearance of text on the printed page. Most printers come
with built-in fonts called internal or resident fonts. Some
dot-matrix printers may only have a few resident fonts,
while some laser printers may have dozens. In addition,
laser and inkjet printers can use soft fonts that come with
your software applications.
|
|
Color.
Color spices up most printed documents, but it can
significantly increase the cost of printing. Not only do
color printers cost more, but the ink, toner, or ribbon
cartridges cost more as well. Although the cost of laser
color printers is coming down, color inkjet printers still
offer the best combination of cost effectiveness and print
quality.
|
|
Maintenance.
The amount of time you spend cleaning a printer, refilling a
paper tray, or changing a toner cartridge may vary greatly
from printer to printer. |
Laser Printers
Laser printers are
similar to copy machines--they use laser beams to burn special toner
onto the page to create a permanent impression. They create
high-quality output at a relatively fast speed, without making too
much noise. The downside is the price; most black-and-white laser
printers cost $500 or more, and each toner cartridge (which lasts
about 3,000 pages) can cost an additional $50.
When considering a
laser printer, here are some things to keep in mind:
 |
Laser
printers offer resolutions ranging upwards from 300 dpi-600
dpi is common, and very high-quality printers can output at
resolutions as high as 3,386 dpi!
|
 |
Laser
printers are available in speeds of 4, 8, or 12 ppm.
However, keep in mind that these are the top speeds. The
actual speed will depend on whether you are printing plain
text, or complex characters and images.
|
 |
The
amount of desk space a printer uses is called the footprint.
If you don't have much room, you'll want a small footprint
printer.
|
 |
Some
printers can hold only 50 sheets of paper, while others can
hold 250 sheets. Some have more than one paper holder, which
increases capacity, and makes it possible to switch between
different sizes of paper. That means you don't have to
reload when you want to print legal size pages or envelopes. |
Inkjet Printers
Inkjet printers
spray a fine, quick-drying ink through small nozzles to produce
characters and images on paper. Although the results are not quite
as sharp as those of laser printers, inkjet printers provide very
good quality output at a lower cost. Laser printers cost more
than other printers, but they may be worth the price because they
are fast, quiet, and produce high-quality text and graphics.
When considering an
inkjet printer, here are some things to keep in mind:
 |
Inkjet
printers are quiet.
|
 |
Inkjet
printers, which start at about $200, are less expensive than
laser printers, yet produce output almost as well.
|
 |
Inkjet
printers are slower than laser printers, but faster than
dot-matrix printers.
|
 |
Replacement
ink cartridges are expensive, costing about $45 each.
|
 |
Many
inkjet printers can use color ink cartridges. |
Dot-Matrix Printers
Dot-matrix printers
are the cheapest printers available. They create text and images on
the page by hammering several small pins against an inked ribbon.
The more pins used, the better the image--9-pin and 24-pin are
common options. The 24-pin printers produce a better quality output,
but are somewhat slower than the 9-pin printers.
Print quality for
dot-matrix printers is often described in terms of mode: draft mode
(low resolution), near-letter-quality mode (medium resolution), or
letter-quality mode (high resolution). The speed depends on the
mode, with draft mode being the fastest.
When considering a
dot-matrix printer, here are some things to keep in mind:
|
Dot-matrix
printers are the cheapest. Prices start at about $100; the
ribbon cartridges last a long time and cost about $15
apiece.
|
|
The
sound made by the pins banging away can be quite loud;
24-pin printers are louder than 9-pin printers.
|
|
Most
dot-matrix printers can use different types of paper,
including continuous feed as well as cut-sheet paper. In
addition, they can be used to print on multipart forms. Some
let you switch back and forth between the different types
without reloading.
|
|
Narrow
carriage dot-matrix printers can accommodate standard letter
size paper, while wide carriage dot-matrix printers can
handle 11x17-inch pages. Wide carriage printers cost
generally about $100 more than narrow carriage
printers. |
Connecting Your Printer to Your
PC
Most printers have
two cables: one is a power cord, and the other is the printer cable.
Connecting a printer involves attaching the printer cable to the
correct port on your computer's system unit, then plugging the power
cord into an electrical outlet.
To attach a printer
cable to the system unit, follow these steps:
- 1. Locate
the printer cable. The easiest way is to find the one that isn't
a power cord. It is probably heavy, gray, about six feet long,
and it ends in a D-shaped connector with 25 pins.
NOTE: For
laser and inkjet printers, the printer cable is probably
permanently attached to the printer. For dot-matrix printers, you
will have to manually attach one end of the cable to the printer.
Locate the end that is not the D-shaped 25-pin connector
and attach it to the port on the printer. Secure it using two
clips that snap into place.
- 2. Locate
the parallel port on the system unit. The parallel port also has
25 sockets, arranged in the same configuration as the 25 pins on
the cable connector.
-
- 3. Plug
the connector on the cable into the port on the system unit.
4. Secure the connector by tightening the screws on
either side.
Understanding Your Printer
Controls
Although most
commands that affect your printer come from your PC and your PC
applications, most printers also have a set of controls. For
example, you may be able to select the mode of operation as well as
which paper tray to use for a particular print job. Status lights on
the front of the printer let you know which controls are active.
If you look at the
front of your printer, these are some of the controls you are likely
to find:
|
Online
or ready light.
A printer must be online in order to work, which means it
must be active and ready to accept data from the computer. |
NOTE: Although
some printers automatically come online when you print a file,
most have an on/off switch. If none of the status lights on your
computer are lit, locate the on/off switch and turn the printer
on.
|
Mode
indicator.
Dot-matrix printers are likely to have different modes such
as draft mode, near-letter-quality mode, and letter-quality
mode.
|
|
Error
indicator. If there
is a problem with printing such as no paper, or a paper jam,
the error light will be lit. |
Be sure to read the
documentation that comes with your printer for complete instructions
on using the printer controls.
Installing Your Printer to Work
in Windows 95
Windows 95 uses the
Add Printer Wizard to assist you in installing a printer. If your
printer is not already installed, run the wizard to add the printer.
NOTE: These
instructions are for installing a local printer, one that is
attached directly to your computer. If you have a networked
printer, ask your network administrator for information about
installing it for use with your computer.
- 1. Double-click
My Computer and then double-click the Printers folder icon.
Double-click the Add Printer icon to start the Add Printer
Wizard. Choose Next.
2. On the second screen of the wizard, select the Local
Printer option button to install a printer directly attached to
your computer. Then click Next again.
3. Select the printer's manufacturer in the Manufacturers
list box. Select the specific printer in the Printers
list box and then choose Next.
NOTE: If
your printer is not on the list, either choose the Generic
manufacturer and Generic/Text Only printer, or click the Have
Disk button and follow instructions to install a vendor-supplied
driver.
- 4. Choose
the printer port, typically LPT1, and then click the Configure
Port button. Check the Spool MS-DOS Print Jobs and the Check
Port State Before Printing check boxes. Choose OK and then
choose Next.
5. In the Printer Name text box, type a name for
the printer or keep the name that is displayed. Select the Yes
option button if you want Windows-based programs to use this
printer as the default printer. (If a different printer is the
default printer, choose No.) Choose Next.
6. Select Yes if you want to print a test page,
and then choose Finish. The test page prints (if you selected
Yes). The wizard copies the printer drivers to your system,
prompting for the Windows 95 disks or CD if needed.
After you install a
printer in Windows, you can make changes to the configuration to
customize it for different printing requirements. You make these
changes in the printer's Properties dialog box:
- 1. Click
the Start menu, select Settings, Printers, and
then select the printer icon for the printer you want to
configure.
2. Right-click the printer icon and then select Properties
to open the Properties dialog box
-
-
Windows 95
makes it easy to install a new printer by using
the Add Printer Wizard. Just pick the right make and
model from the list.
- 3. The
Properties dialog box contains several tabs. Select each tab to
view the settings. Click the Help button (the question mark in
the upper-right corner) and then click a feature to read details
about that property. Properties vary according to each printer's
capabilities.
4. Change settings as desired, and then choose OK to save
the new settings. Choose Cancel to get out of the dialog box
without making any changes.
If you no longer
need a printer that is installed in Windows 95, you can delete it
from the Printers folder window:
- 1. Double-click
My Computer and then double-click the Printers folder icon.
2. Select the printer you want to delete. Open the File
menu and select Delete.
3. Windows asks if you are sure that you want to delete
the printer. Choose Yes. The printer icon is deleted.
4. Windows then asks if it can remove files that were
used only for this printer. Choose Yes. (If you plan to
reattach this printer in the future, choose No.)
Other Printing Considerations
Printing a document
is similar in most Windows applications. You can open the
application's File menu and select Print to open the
Print dialog box. In the dialog box, you can select options such as
which pages you want to print and how many copies to print. To
quickly print the current document without setting options, click
the Print button on the toolbar.
A printer icon on
the taskbar near the clock indicates that printing is in progress. A
quick way to check the status of print jobs is to point to the
printer icon on the taskbar.
After you issue the
print command, the Print Manager takes control of the print job.
You can use the commands in Print Manager to check the status of a
print job, to cancel a print job, or to pause a print job.
Print Manager
keeps track of documents waiting to be printed.
There are several ways to open Print Manager:
|
If
a print job is in progress, double-click the printer icon in
the taskbar.
|
|
Click
the Start button and select Settings, Printers.
Then double-click the printer icon for the printer you want
to manage.
|
|
Double-click
the My Computer icon and then double-click the Printers
folder icon.
Double-click the printer icon for the printer you want to
manage. |
If your printer is
not working, here are a few things to check:
|
Is
the printer turned on?
|
|
Is
the printer online?
|
|
Are
the cables between the printer and the computer attached
correctly and securely?
|
|
Is
the printer power cord plugged in?
|
|
Is
there paper in the printer?
|
|
Has
the printer been paused in the Print Manager? |
TIP: To
check if a printer has been paused, open the Print Manager, then
open the Printer menu. If there is a check mark next to the
Pause Printing command, the printer has been paused. To
restart it, select the Pause Printing command.
