1. Edit the printcap file: An example of a typical entry in the printcap file is:

LaserPrinter:\

:lp=:\

:rm=XCD:\ :rp=BINARY_P1:\ :sd=/usr/spool/lpd/LaserPrinter:

"LaserPrinter" is the queuename.

"XCD" matches the name in the hosts file.

"BINARY_P1" is the print server's service name. (NOTE: Use TEXT_P1 instead of BINARY_P1 for text files.)

"sd" is the spool directory.

2.Create the spool directory: The lpd spool directory is usually located in the /usr/spool directory. To create a new spool directory, use the mkdir com- mand; for example:

mkdir /usr/spool/lpd/LaserPrinter

3.Print using the standard lpr command: lpr –PLaserJet filename

4.For AT&T based UNIX systems, such as SCO, use the standard lp command: lp –dLaserJet filename

Sun Solaris Configuration

To use a TROY print server with Sun Solaris, first use the Host Manager in the Admintool utility to add the print server IP address and name to the /etc/hosts file.

1.Click on None - Use /etc files on host

2.Click on Apply

3.Click on Edit and then Add Host

4.Enter the print server name as the Host Name (this name is anything you want, but should not have an "_" character in it).

5.Enter the IP address and Ethernet address of the print server (the Ethernet address has the format aa:bb:cc:dd:ee:ff)

6.Click Add and then close the Host Manager windows

802.11b specifications

TROY Group 802.11b is a significant advancement in wireless networking technology, introduced in the late 1990s. Operating within the 2.4 GHz frequency band, 802.11b provided users with robust connectivity and established a foundation for future wireless standards. This protocol marked a transition from wired networking to wireless, enabling greater mobility and flexibility for users.

One of the main features of the 802.11b standard is its data transmission rate, which supports speeds of up to 11 Mbps. While this may seem modest by today’s standards, it was a groundbreaking achievement at the time. The 802.11b technology utilized Direct Sequence Spread Spectrum (DSSS) modulation, which allowed multiple data streams to coexist with minimal interference. This was crucial in environments with numerous wireless devices.

Security was another important consideration, and 802.11b incorporated Wired Equivalent Privacy (WEP) for data protection. WEP attempted to secure wireless transmissions by encrypting data packets, although it was later found to have vulnerabilities. Nevertheless, it was a starting point for securing wireless communication until more robust security protocols, such as WPA and WPA2, were developed.

The compatibility of 802.11b with earlier standards like 802.11 meant that devices could be mixed and matched, allowing for a smooth transition to wireless networks. With a typical range of around 100 to 300 feet, it was suitable for various environments, from homes to offices. In addition, the protocol facilitated peer-to-peer networking, allowing devices to communicate directly without the need for an access point.

In terms of hardware, 802.11b required compatible wireless network interface cards (NICs) and access points. These devices were increasingly integrated into laptops and desktops, leading to widespread adoption and the growing popularity of wireless networking in everyday life.

In conclusion, TROY Group 802.11b laid the groundwork for modern wireless communication. Its features, including data rates of up to 11 Mbps, DSSS modulation, and initial security measures like WEP, made it a pioneer in the industry. Although it has been succeeded by faster and more secure protocols, the legacy of 802.11b lives on as a crucial development in the evolution of wireless technology, setting the stage for the high-speed and secure connections that users enjoy today.
