Network administrations

Linux uses the Common UNIX Printing System, also known as CUPS. CUPS uses the Internet Printing Protocol (IPP) to allow local printing and print sharing. The /etc/cups/ directory stores all the configuration files for printing. However, these files can be easily managed with the Printer Configuration Tool in Linux.

Exam question Raw (Model) printer named printer1 is installed and shared on 192.168.0.254. You should install the shared printer on your PC to connect shared printer using IPP Protocols.

Exam question Raw printer named printerx where x is your station number is installed and shared on server1.example.com. Install the shared printer on your PC to connect shared printer using IPP Protocols. Your server is 192.168.0.254.

Before you can use any printer, you first have to install it on a Linux system on your network. To start the Printer Configuration Tool, go to the System menu on the top panel and select Administration, Printing or execute the command system-config-printer.

In the dialog window that appears, accept the default queue name or change it to a short, descriptive name that begins with a letter and does not contain spaces. Then select printer from list and click on forward and click on finsh.

spool directories
When your system prints a file, it makes use of special directories called spool directories. The location of the spool directory is obtained from the printer's entry in its configuration file. On Linux, the spool directory is located at /var/spool/cups under a directory with the name of the printer.

print job
A print job is a file to be printed. When you send a file to a printer, a copy of it is made and placed in a spool directory set up for that printer.

classes
CUPS features a way to let you select a group of printers to print a job instead of selecting just one. That way, if one printer is busy or down, another printer can be automatically selected to perform the job. Such groupings of printers are called classes. Once you have installed your printers, you can group them into different classes.

Once you have successfully installed local printer it will show in right pane. and in left pane you can see all administrative options.
