Printing

There are currently two postscript Laser printers and one color DeskJet available to the theory group.
The default printer (i.e. if you don't specify a printer) is duplex.

The HP LaserJet 4250 is located in 446 Lauritsen. The two queues are set up for single-sided and double-sided printing.

The HP LaserJet 8100 is located on the Downs side of the building.The two queues are set up for single-sided and double-sided printing.

The DeskJet 1220c is our color printer, located in the same room as the LaserJet 4250 and the Windows PC. The queue color is intended for pages with text and figures such as slides or papers. The queue color-photo is intended for color photograph and colord is for double-sided color printing.

General Printing Tips

From the command line you can print a postscript or ascii fileusing

lpr -P queuename

where queuename is the name of thequeue on one of our printers. If you do not specify a queue then the default is duplex on the HP LaserJet 4250.

If you want to print multiple pages per side you can use the following command

psnup -h26cm -N filename | lpr -Pprintername

where N={2,4,8} is number of pages per side, and printername is your your choice of printer (duplex or downsd for double sided printing).

To simplify the above, you can also use the command lpr2d instead of lpr to get two pages per side, duplex printing on the LJ4250.

Printing from within programs

Ghostview: The most common use of the printer is for papersbrought up in Ghostview. When you go to File-Print, ghostviewpops up a window asking for the printer name All you need to dois enter the name of the print queue you wish to use.

Gv: This is an alternative to ghostview which you can use by runninggv filename. When printing from it, a window will pop upwith the words lpr. You can append -P queuename to specify a different printeror substitute lpr for any of the above duplex printing commands.

Acroread: If you have a pdf file that you wish to print fromAcroread then the syntax is slightly different than other applications.When you hit print you'll see the print command:

usr/bin/lp -c

To print to a queue other than the default you need to add-d queuename.

Note that sometimes pdf files are excesively complicated and pose problems for the printer. In this case it is best to print only a few pages at a time.

Mathematica and Netscape: In these you will have the option to eitherprint to a file, or enter a command as in gv above.

Printing from other applications will likely be similar toone of the above cases.
