What is the "one-up" option in the Commercial PDF options?

One-up printing forces only one copy to be printed per page.

By contrast, when using our standard print options, postcards will print two-up, or two per page, and our property cards will print six-up, or six per page.

Select the one-up option if your printer is unable to properly print the project with the standard options and/or when you want to print only one copy of the project per piece of paper/stock.
