Traditional UNIX Printing generate, create code128 none on .net projects Bar Code Types Before the adve VS .NET ANSI/AIM Code 128 nt of GUIs and WYSIWYG (page 1116) word processors, UNIX users would create documents using an editor such as vi and a typesetting markup language such as TeX or nroff/troff, convert the resulting files to PostScript using an interpreter, and send the PostScript files to the printer using lpr (BSD) or lp (System V). Fedora/RHEL implements both BSD and System V command-line printing utilities for compatibility.

However, these utilities are now wrappers around the equivalent functionality in CUPS rather than core components of the printing system. The corresponding utilities are functionally equivalent; use whichever you prefer (Table 14-2). From the command line, you can print a text, PostScript, or PDF file using lp:.

$ lp memo.txt r equest id is MainPrinter-25 (1 file(s)). Traditional UNIX Printing 531 Figure 14-12. Printer page showing jobs information Table 14-2. BSD/SysV lpr/lp lpq/lpstat lprm/cancel BSD and System V command-line print utilities Purpose Sends job(s) to the printer Displays the status of the print queue Removes job(s) from the print queue. The preceding c Code128 for .NET ommand adds memo.txt to the print queue of the default printer as job 25.

When this printer is available, it prints the file. You can specify a printer using the d option:. $ lp -d ColorPt r request id is ColorPtr-26 (1 file(s)). The lpr P opti Code 128C for .NET on is equivalent to the lp d option. Without arguments, lp and lpr send their standard input to the printer:.

$ cat memo2.txt lp request id visual .net Code-128 is MainPrinter-27 (1 file(s)). The lpq and lps tat commands display information about the print queue:. 532 14 Printing with CUPS $ lpstat MainPr inter-25 ColorPtr-26 MainPrinter-27. zach zach zach 13312 75776 8192.

Configuring Printers You can use the Web interface or the command-line interface to CUPS to manage printers and queues. The CUPS Web Interface To connect to t .net vs 2010 Code 128A he CUPS Web interface (page 527), point a Web browser running on the local system at localhost:631. You must supply the username root and the root password to change the printer configuration using the CUPS Web interface.

. Modifying a Printer JumpStart II: barcode 128 for .NET Setting Up a Local or Remote Printer Using the CUPS Web Interface (page 527) discusses how to set up a printer using the CUPS Web interface. This section explains how to modify a printer that is already set up.

To modify a printer, click the Printers tab near the top of the page and then click the name of the printer you want to modify. The CUPS Web interface displays two drop-down lists near the top of the page: Administration and Maintenance (Figure 14-12, page 531). These lists work with the selected printer.

The Administration drop-down list allows you to modify the printer; this selection takes you through the same steps as when you set up a new printer. From this list you can also delete and set default options for the printer as well as set the printer as the default printer and specify which users are allowed to use the printer. From the Maintenance drop-down list, you can print a test page and pause the printer.

You can also reject, move, and cancel all jobs.. Jobs Click the Jobs barcode 128 for .NET tab near the top of the page to display the Jobs page, which lists jobs in the print queues. From this page you can cancel print jobs and move them to other queues.

Click Show Completed Jobs to display a list of recently completed jobs. In some cases, you can reprint completed jobs from this page. You can perform the same tasks from the Printer page.
