• Linux
  Linux printers are accessed through the Common Unix Printing Systems (CUPS) by pointing the local CUPS system at scroll. To do this add a line in /etc/cups/client.conf:
  ServerName scroll.stanford.edu
  This line is added automatically if you install the graphics version of CentOS.
  
  Additionally, you can use the lp, lpstat and cancel commands from the terminal to print (even if you haven't installed the printer). For example:

  $ enscript -p - myfile.txt | lp -d offset -h scroll.stanford.edu -

  will print "myfile.txt" to offset.

  Apple MacOS
  Open up the "Printers & Scanners" preference pane. Click the "+" to add a new printer. In the resulting dialog, choose "IP Printer" and enter the following information:

  • Protocol: Line Printer Daemon - LPD
  • Address: scroll.stanford.edu
  • Queue: Name of the printer, for example letterpress
  • Name: Name of the printer, for example letterpress
  • Location: Leave Blank
  • Print Using: Select make and model of printer.
    The default Apple driver, Generic Postscript, which works for ordinary printing, but be sure to check the "Duplex" box when prompted.
    Or: Choose the driver for the printers above with the Select Printer Software... dialog after first installable HP driver bundle

  
  Then, click Add. Depending on the printer, you will likely be presented with an additional dialog to select installed options. For our printers, you'll want to check the "Duplex Unit" option
  Note: However, to actually get duplex printing, you will have to later create a Preset with the Two-Sided option checked using the Apple printer dialogs.

  Microsoft Windows
  The lab no longer supports Windows native printing. You will not be able to just navigate to the printer in the Windows GUI as in the past. You can use the built-in website at each printer to navigate to HP to download drivers or download the HP Universal Print Driver

  To set up the CUPS printers, first open up "Printers and Devices"

  • Select "Add Printer"
  • Select "Add a network, Wireless or Bluetooth printer"
    Skip the detection and select "Next".
    
  • "Find a printer by name or IP address"
    Choose "Select a shared printer by name".
    The printer name is a URL of the form http://scroll.stanford.edu:631/printers/PRINTERNAME
    where PRINTERNAME is the printer in question as it appears on the CUPS printer status web page, e.g. letterpress.
    There will be a noticeable pause while the client connects to the server and downloads the printer information.
    Follow the ensuing prompts, using the HP universal PCL6 driver or selecting the driver as for a specific printer above.
  • Setting Printing Defaults
    After the install, you can use the "Properties" dialog to describe details about the printer's capabilities, e.g. duplexing. One thing worth doing, especially if you print large jobs, is to set the print scheduling to go "directly" to the printer. This avoids spooling the jobs on your local disk since they'll be spooled on scroll anyway.
    To set device defaults, select (highlight) a printer, pull-down "File" and "Document Defaults" and you can set things like duplex or grayscale. This is important since Windows always configures the printer for each job, so even though the laser printer "letterpress" is normally set in duplex, you can default to single-sided printing in Windows.
    Set the defaults you want as you can override them for single documents easily in the Print dialogs of applications like Word.
    The list of all jobs in the print queue is available for each printer. You may cancel any jobs that you own before they print.

There are a number of printer GUIs available for Linux. The nicest at the moment is kprinter which is part of the KDE package (and is the default printing dialog of any KDE program). You can use it from within other programs by using "kprinter" as the printer command (use "kprinter --stdin" if the program pipes the input to the print command). The program xpp also has similar functionality, but a much uglier interface. However, it does not require KDE.

Printing Plaintext Files

To quickly print text files 2up, use:

     a2ps -2 file.txt

Transparencies

On "tone", transparencies shouldn't be put into the tray. Rather, you should open both the auxiliary input and output tray doors on the right side to feed and retrieve the slides. This method shortens and straightens the paper path through the printer so that you minimize crumpling.

Printing to special paper

letterpress doesn't wait very long for you to load paper into the manual feed tray, so load your paper before printing (this can change if people complain). letterpress will pause when the manual feed job is to be printed and waits until either paper is loaded or the big round button is pushed.
