Wireless Networks

Notes The computer that has both adapters also has an Internet connection. This connection can be via
Dialup modem, cable modem, DSL, ISDN or any other method to connect to the Internet. This
well-connected computer will be used as the MMR. The Mixed Media Router manages the data
flow among the three networks that use different connection media, so that a single Internet
connection will be shared among the computers in all the sub networks, and File and Printer
sharing will work.

6.4 Printing

Wireless printing is a cost-effective way to easily and flexibly produce barcodes wherever you
are. Virtually any printing application can go wireless – especially situations where cabling is
either inconvenient or impossible. Realize great benefits from wireless printing technology.

Notes Bluetooth wireless printing is a proprietary open wireless technology standard for
exchanging data over short distances from fixed and mobile devices.
Wireless LAN 802.11b or 802.11g provides for secure data transfer of sensitive information.

Here are three ways to turn any printer into a wireless one.
1. Plug into a wireless print server: If your printer has a USB port, you can plug in a wireless
print server, a small box into which you can connect your printer. The advantage of
investing in a print server is that you don’t have to connect the printer to a PC, which
means you can use your laptop and print anywhere in your home. During the setup, you
will have to plug the printer into the printer server, and connect that to the router using an
Ethernet cable. Meanwhile, you’ll have to install software on your computer and configure
the connection, as you would when setting up a router.
