● There will be runners who will deliver printed output to your team workstation (teams will not have direct access to the printers).

● To generate printed output, use the printfile command (see below). Printing files from within IDEs and other applications may work but is not guaranteed.

● To use the printfile command, go to a command prompt (open a shell terminal window) and type

printfile <filename>

where <filename> is the name of the file you want printed. Print jobs are limited to a few pages long; printing excessively long output will be deemed an activity detrimental to the contest and subject to disqualification.

Additionally, teams are allowed to bring their own notebook consists of 25 one-side printed A4 pages.
