Overview
DeltaWMS will use the printers set under printing in the Preferences tab in the DeltaWMS app, which can be found as below:
Click File
Then Preferences
Then click the Printing tab.
📌Note: This will determine the preview of the reports when run in DeltaWMS.
🤓Tip: If the default printer set is not the printer set under Preferences in DeltaWMS, this would also cause the reports to always show in Portrait and not landscape.
