How to customize PageMediaSize when printing with print support app
I am having problems customizing the size of a page when printing with a virtual printer on PSA. In fact, I can only change the size of the printed page through the PrintTicketFeature PageMediaSizeFeature options. But the app I am developing currently needs an additional function that allows users to define the size of the printed page themselves. I am having trouble here, although I have read the PSA guide (https://learn.microsoft.com/en-us/windows-hardware/drivers/devapps/print-support-app-v4-design-guide), I still cannot implement customizing the size of a page when printing with a virtual printer on PSA. Can you help me with this problem?
