Printing Tasks

Task Commands Remarks
print a document from a GUI application (e.g. standalone PDF reader)
  • press Ctrl-P (in Unix or Windows)
  • press Command-P (in MacOS)
  • select the queue name from the above list of public printers
  • please consider the environment before printing
  • printing books is not allowed
  • use Canon copiers for instructional jobs
  • send large jobs to one of Canon printers
  • use two-sided printing option (save trees)
  • sometimes, a (malformed) PDF document won't print from the web browser, but prints OK from a standalone PDF viewer (e.g. Mac Preview or Linux Document Viewer)
  • the Canon printers won't print A4 paper size PDF documents without shrinking or cropping the documents to fit the US Letter size
print a document from Unix command line
  • lpr -P queue file
  • replace queue with the queue name from the above list of public printers
  • replace file with the file path of the document to print
check the print queue status from Unix command line
  • lpq -P queue
  • replace queue with the queue name from the above list of public printers
cancel the job from Unix command line
  • lprm job
  • replace job with the job number from the above output of lpq command
  • you have to own the job in order to able to cancel it
add a printer to personal Windows computer
  • go to Add Network Printer dialogue
  • use the URL from the above list of public printers
  • use a proper Postscript driver (see remarks)
  • do not use PCL printer drivers, use Postscript drivers instead
  • it is recommended to install the HP universal Postscript driver for HP printers
  • it is recommended to install the Canon Postscript driver for imageRunner Advance printers
add a printer to personal Mac computer
  • go to the list of printers in System Preferences
  • click on + sign
  • click on the IP tab
  • select IPP protocol
  • type printserver.math.berkeley.edu in Address
  • type printers/queue in Queue
  • type queue in Name
  • select Generic Postscript Printer
  • click on Add button and check the Duplex Printing Unit
  • click on OK button
  • replace queue with the queue name from the above list of public printers
  • Generic Postscript driver generally works fine for both HP and Canon printers but does not support some features
  • download and install a proper Canon Postscript driver if you want to use the stapler function
