In Adagio Checks, the default printer is defined from Options under the File menu. This is the way to assign printing checks to a particular printer other than the Windows default. If you make any changes to the printer location within the print checks function, these changes are not remembered.

Note that for Adagio Checks, this default printer is defined 'company-wide', meaning that any Adagio Checks user attempting to print checks will have that specific printer used as the default. This isn't a problem if only one workstation will be used for printing checks.
