Department Print Server
Departmental printers can be accessed via our print server printhost.cs.brown.edu. You can access this print server from any departmental network, the CIS wireless network, or when connected through the CS VPN. It hosts a variety of print queues for all the department network printers. See the printing policy for usage limitations.

See the Printing in the Sunlab page for more information.
Authenticated printing over the wireless network
There is a split dns setup for printhost.cs.brown.edu. Inside the department, printhost resolves to printhost-int. Externally, printhost resolves to printhost-dmz, the authenticated print server. The authenticated print server allows printer connection from all Brown internal and wireless networks.
If you print from a self managed machine over the wireless network, you will be required to enter your LDAP credentials. You can log on to web interface with your LDAP credentials to view a complete list of available print queues, the status of each printer, and current list of pending jobs.
For instruction on how to set up the printer connections over the wireless network, see the "Printer Mapping Instruction for Self Managed System or over Wireless network" section below.
Tstaff Managed Systems
All managed department machines are configured to use the internal print server. No user configuration is required.
As with many things in Linux, there are quite a few printing commands. Some of the most important are:
- 'lpstat -a': show the list of printers available on the print server
- 'lpr': send a file in text, postscript or pdf format to the printer
Viewing the current jobs in a Linux print queue
You can view the current jobs in a Linux print queue by running:
lpq -P<print queue>, where <print queue> is the name of the queue (e.g. bw4).
The command will return something similar to:
bw4 is ready and printing

In Windows, most programs let you print from the File-Print menu of that application. To see the list of printers, go to the Start Menu, select Control Panels, and then Devices & Printers. All printers are available except for the clf4hq printer.

Other Printing Issues
If you encounter a physical problem with a printer (jammed, out of toner or ink, etc) and have not been ``trained'' in how to fix the problem, please do not try to guess your way through. Use the problem facility to report the trouble, or ask a Tstaff member or one of those friendly veteran grad students. They'll show you how to fix it for the next time. Be especially hesitant to mess with the color printers.
If your printout is on the wrong type of paper
Occasionally, if you specify a certain type of paper and that tray is empty, the printer will automatically default to a different paper tray.
If your printout ends up printed on a different type of paper than you expected, you might want to check the paper trays and make sure none of them are empty.
How to print an A4 sized PostScript file
Our printers print only on US Letter sized paper. Most European countries print on A4 sized paper, which is taller and narrower. Electronic documents formatted for A4 often will not print properly, or at all, on our printers.
When printing an A4 document from a browser or application on any platform, it will be helpful to preview it and, if necessary, to scale it down before sending the job to the printer.
The easiest way around this is to transform the A4-size document into a Letter-size document before printing it. How you do this depends on the format the document is in. If, for example, the document is a Framemaker document, you may find it easiest to reformat the document in Framemaker. The same goes for Microsoft Word, or Acrobat or many other document formats.
How to print an A4 sized PostScript file in Linux
In Linux, you can reformat any A4 postscript document using the following simple command. Most desktop publishing applications let you save a document as PostScript, usually from the Print menu. If the document is already in PostScript format, or if you cannot reformat it in some other way, try this.
Let's say our A4 document is called euro.ps:
% mpage -1o euro.ps> amer.ps
% lpr amer.ps
The resulting file, amer.ps, is in US Letter format.
