Mathematics Computer Farm: Printing Help
What Can Be PrintedThe department printers accept plain text and PostScript files only, hence to make the printing as simple as possible for a Windows user, we have built a system that automatically performs all necessary preparations conversions.
All the user has to do is to apply some common sense and print only files which produce a PRINTABLE result: text and pictures.
Thus, any format that produces text and pictures, such as: .txt, .cpp, .html, .pdf, .ps, .doc, .xls, .bmp, .jpg, .gif, etc., is acceptible.
Obviously, there is no point in sending .exe, .zip or movies files to the printer, as the only result of such actions is a waste of paper and printer resources.
Users who wish to print directly from their Unix account using the "lpr" command, should double check before printing, that their file is either text or Postscript.
WARNING: Accidental printing of binary files wastes much paper and uses up your quota. You should try to verify that the files you wish to print are ACTUALLY PRINTABLE before printing them.
Printing from WindowsFrom the Windows computers in the computer farm you print by choosing the relevant Windows application Print command and then choosing the Print to Public Printers printer from the available printers list.
A new window will popup, and you will need to enter or choose the following four pieces of information:
- Host (where you have your UNIX account: t2, tx, fermat);
- Printer (the printer/queue to send to);
- Login (your UNIX login name on the chosen host);
- Password (your password to that account).
It will take a few second for the job to be processed, and after this is done the window with will disappear.
If the data you entered is correct, and if you have no over quota, this means that your job had entered the printing queue and is about to come out of the printer.
Note that to check the status of the queue or delete a job you MUST use the UNIX commands.
- lpr: The command "lpr -Pprinter FileName" sends FileName to the specified printer.
For example, typing "lpr -Pmastudp MyFile.ps" will send MyFile.ps to the printer mastudp.
- lpq: The command "lpq -Pprinter" allows you to check the status of the queue of the specified printer . It will show the list of pending jobs in the queue.
For example, typing "lpq -Pmastudp" will show the list of pending jobs of the printer mastudp.
- lprm: The command "lprm -Pprinter jobNumber" delete jobs from the queue. Where the jobNumber is the number that appears in the fourth column ("Job") of the output of lpq. Users can only delete jobs printed from their own account.
How to deal with problems when trying to print a file
- Ask an Adviser.
