Printing with

You can use the lpr command to print documents to both local and remote printers (provided the printers are configured locally). Document files can be either added to the end of the lpr command line or directed to the lpr command using a pipe (|). Here's an example of a simple lpr command:

When you specify just a document file with lpr, output is directed to the default printer. As an individual user, you can change the default printer by setting the value of the PRINTER variable. Typically, you add the PRINTER variable to one of your startup files, such as $HOME/.bashrc. Adding the following line to your .bashrc file, for example, sets your default printer to lp3:

export PRINTER=lp3

To override the default printer, specify a particular printer on the lpr command line. The following example uses the -P option to select a different printer:

$ lpr -P canyonps doc1.ps

The lpr command has a variety of options that enable lpr to interpret and format several different types of documents. These include -# num, where num is replaced by the number of copies to print (from 1 to 100) and -l (which causes a document to be sent in raw mode, presuming that the document has already been formatted). To learn more options to lpr, type man lpr.
