Enable System Print dialog in Edge browser
Using Registry Editor
These are the steps to enable the System Print Dialog in Edge: In the first step, you need to open the Registry Editor window. Once that window is opened, go to the Edge key. Its path is here:
You might need to create a Registry key and name it Edge if that key is not available already. Now right-click on the right section of the Edge key, access New, and use DWORD (32-bit) Value. This will create a new DWORD value. Rename it to UseSystemPrintDialog.
Double-click on UseSystemPrintDialog. When a small box appears, add 1 under Value data, and press OK.
Now either restart PC or restart File Explorer to save the changes. Open Microsoft Edge and take a print. You will notice that the System Print dialog is opened instead of the Print dialog of Microsoft Edge. To disable the System Print dialog for Microsoft Edge, you can follow the above steps, and then delete the UseSystemPrintDialog value. Restart PC or File Explorer to apply the changes.
