I have PAX A920 Device for printing invoice, and we have odoo POS system. When I click print button from chrome browser it is opening default printing Service of android which not detect build in printer in Device. I want to know can I open my custom application for Triggering print function of build in printer, or is there any other option to configure or detect Default Print Service of Android
What do you mean by "it is opening default printing Service of android"? to me it looks like it just opens the pdf and let you save it. As far as I know the browser does not send a "print request" since usually android devices cannot print anything.
What you could do is make your app compatible with pdfs so you can choose to open a pdf with your app which then prints it automatically
