APM Laser Command ----------------- The command "laser" can be used for placing, examining, and deleteing files from the laserprinter queue. This command is only available on the 'B' filestore to users who have been accredited. Printing a File --------------- To print a file type "laser" or "laser filename". In the former case, or if the file is not found, the program will prompt for a filename. Extensions are added automatically. Known extensions are: .lay .san .dvi .pdf. Typing a return in response to the filename prompt will bring the user back to command level. The message "filename queued for laserprinter" will appear when a file has been found to print. You will notice that the name of the file is changed to the name of the user printing the file plus a unique 2 digit number, a letter and possibly an extension. Examples: } laser report DMB14A.dvi queued for laserprinter } laser jim Jim not found Filename: report.dvi DMB15A.dvi queued for laserprinter } laser pub:letter DMB76A.lay queued for laserprinter Deleting a file from the queue ------------------------------ To delete a file from the queue the "-DELete" and "-ENTry" qualifiers can be used (the capitals show the minimum you have to type). Typing "laser-del" will delete the first file belonging to you from the queue. If you have more than one file in the queue you can delete the nth entry by typing "laser-del-ent=n", the default for entry being set to 1. Typing an entry number that does not exist will produce an error. Examples: } laser-del lp1:dmb14A.dvi deleted } laser-del No files found } laser-del-ent=3 2 of your files in queue, couldn't delete entry 3 Looking at the queue -------------------- To examine the queue type "laser-Queue" (As above only the 'q' is needed). Examples: } laser-q Laserprinter queue: DMB168.dvi TEXT421.san JIM983.lay FRED123 } laser-q Laserprinter queue: Empty Special Parameters for DVI files -------------------------------- A special parameter -dvi="" exists to allow printing qualifiers to be used when printing the dvi file, e.g. range of pages, margin offset etc. For the full list of parameters available see the document `Using TeX in the CS dept.' A second file is created which contains the parameters. If you subsequently remove the dvi file from the queue, the parameter file will automatically be deleted if one exists. Examples: } laser report-dvi="-do=2:5" Pass the parameter "-do=2:5" to the dvi printing program.
