I will do automatic pdf printing in the background using the pdfium library. with the api, it finds the path to the pdf from the database and prints the pdf. but before that, it sets a default printer. (I usually choose Microsoft Print To PDF). then when I click button1, it should print automatically in the background, but I keep getting the Save Output As window. this prevents it from doing it automatically in the background. my goal is to automatically print every pdf that comes instantly from the database. please help me. thank you everyone.
