There are a few ways to set a default label size for your Jadens printer.
Generally, you can use “Last Used Settings” shown below as a preset to print. This will remember the setting that was previously used.
If this doesn’t work for any reason, please follow these steps to set the default size:
Step1: In the Print Prompt Window, under Paper Size, click on “Manage Custom Sizes”.
Step2: Click on “+” to add a new size.
Step3: Create a new size with 4″ x 6″ dimensions. You may double-click on the left to rename this page or something similar.
Step4: Please go to System Preferences -> Printers & Scanners -> Select Label Printer and set the default size.
