| Now that you have completed this chapter, you
should have a firm understanding of the following:
Printing to local and remote printers
is an essential function in a work environment. There are three main components
in the UNIX printing environment: The printer (physical
device), the printer name (print queue) and the print server
(computer that managers the print queue). The system administrator
sets up the printing environment by installing printers and defining
print queues and servers to support them. Printers can be attached to
workstations, servers, or directly to a network hub or switch. The
administrator sets up and manages the printing environment.
When a user prints a document, a print
request is generated. This request passes through the network to the
print server that manages the print queue for the printer name the
user selected. The print server stores the documents on its hard drive
temporarily and then forwards them to the physical printer when it
becomes available.
Files can be printed using the lp
command from the command line or with the CDE File Manager.
There are a number of options available including printer selection,
banner output, and number of copies. With File Manager, documents can
be dragged with the mouse to the printer icon or print manager window
to print them.
Print requests residing in print queues
can be viewed and managed using the lpstat
command or with CDE Print Manager. Users can see their
outstanding requests in the queue and remove them from using the cancel
command or with the graphical Print Manager utility. A user can only
cancel their print jobs. |
