Installation and Configuration of Printers

with printer port. It sends data 8 bits at a time (in parallel) and uses a cable with a male
DB-25 connector at the computer and a 36-bin Centronics male connector at the printer. Its
main drawback is its cable length, which must be less than 10 feet.
Universal Serial Bus (USB) The most popular type of printer interface as this book is being
written is the USB. It’s the most popular interface for just about every peripheral. The benefit
for printers is that it has a higher transfer rate than either serial or parallel and it automati-
cally recognizes new devices. USB is also fully Plug and Play, and it allows several printers to
be connected at once without adding ports or using up additional system resources.
Network Most large-environment printers (primarily laser and LED printers) have a
special interface that allows them to be hooked directly to a network. These printers have
a network interface card (NIC) and ROM-based software that let them communicate with
networks, servers, and workstations.
The type of network interface used on the printer depends on the type of network the printer
is being attached to. For example, if you’re using a Token Ring network, the printer should
have a Token Ring interface.
IEEE 1394/FireWire This is a high-speed serial alternative to USB. It’s less commonly
used for printers than USB is, but FireWire printer interfaces do exist.
Radio Wave Bluetooth is an infrared technology that can connect a printer to a computer
at a range of about 35 feet, provided there is an unblocked line of sight.
Wireless A network-enabled printer that has a wireless adapter can participate
in a wireless Ethernet (IEEE 802.11b, a, or g) network, just as it would as a wired
network client.
Firmware Updates
Printers resemble computers in many ways. Like a computers, they can have their own
motherboard, memory, and CPU. They also have firmware—that is, software permanently
stored on a chip. If you’re using an old computer with a new operating system, an update
may be available for the printer’s or scanner’s firmware. You can find out that information
at the printer or scanner manufacturer’s website and download the update from there along
with a utility program for performing the update.
Printer Configuration
To add a printer, whether it’s local or networked, you start the Add Printer Wizard found
in Windows by accessing Start Printers and Faxes (or Start Printers) and then choosing
Add a Printer. Once the printer is installed, you can right-click its icon at any time beneath
this dialog box and choose Properties from the context menu. From here, you can print a test
page and configure such items as sharing, ports, device settings (including tray selection), and
so on. Figure 1.37 shows the spooling options and the settings that allow you to configure the
printer to be available only at certain times, and Figure 1.38 shows the tray settings.
