Print after Javascript executed


i want to use the cordova printer plugin to print a external website after the javascript is executed.

Do i have to edit the website or is there a possibility to execute the javascript of the website and then get the printer?

Or it is possible to open an system browser (not the InAppBrowser) to print? On the Website there is a button with javascript, which execute the print in browser. This button don’t work for the inappbrowser for me :frowning:

best regards
