To achieve printing multiple items from a gallery to separate sheets using a badge printer in your Power App, you can follow these steps:
In your gallery, make sure you have a checkbox control for each item that the user can select for printing. Bind the Checkbox control to a Boolean variable (e.g., PrintSelected) in the Items property of the gallery.
Create a button or an action that the user will click to initiate the printing process.
In the button's OnSelect property, use the ForAll function to iterate through the gallery items and check which items are selected for printing. For each selected item, navigate to the screen that needs to be printed and handle the printing process.
Here's an example formula for the button's OnSelect property:
ForAll(
Filter(Gallery1.AllItems, PrintSelected),
Navigate(PrintScreen, ScreenTransition.None);
// Handle the printing process for the current item in PrintScreen
// Once printing is completed, navigate back to the previous screen
Back()
)
In the PrintScreen, design the layout as needed for each item to be printed on a separate sheet. You can bind the controls in the PrintScreen to the relevant data for the current item.
Implement the printing functionality in the PrintScreen based on your badge printer requirements. This can vary depending on the printer and its supported methods (e.g., using a specific printer API, generating a print-ready document, etc.). Consult the documentation or resources provided by the badge printer manufacturer for guidance on how to print using their device.
Note: The printing process may involve specific JavaScript code or plugins. You can use the Power Apps Components Framework (PCF) to extend the capabilities of your Power App and integrate with external plugins or libraries if needed.
Once the printing is completed for an item, use the Back() function to navigate back to the previous screen where the gallery is located.
By implementing these steps, you can enable the printing of multiple selected items from the gallery to separate sheets using your badge printer in your Power App. Adjust the printing logic and layout design in the PrintScreen based on the requirements of your specific badge printer and desired output format.
