The 2-part job data sheet printout supports standard 8.5x11 paper. The design of the printout has 2 job portions and upper portion and a lower portion. Printing on paper that is perforated through the middle will allow you to quickly tear and utilize the portion for your needs.
The pictured paper can be purchased from amazon but of course you can purchase your paper from any source.
Some customers have noted that they enjoy using a quad perforation which they note allows for easier folding of the job printout to fit into there job envelopes.
