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
