Match Software releases Check Print'R 3.21, an important update to their easy-to-use check printing application for macOS. Check Print'R allows anyone to create and print checks for up to 15 separate bank accounts. The application can print checks to plain letter-sized paper, or to check refill paper available at most office supply stores. Version 3.21 brings the ability to print the contents of the check register in either portrait or landscape format. Check Print'R 3.21 is $15.99 and can be downloaded from Mac App Store.
