Silent printing from web to specific printer

I need to select a printer using javascript and send a webpage to print silently. I had no time to complete this description and now I add the following: Update: The project can use WebApp Hardware bridge [login to view URL] And html2canvas [login to view URL] with this code ////////////////////////////////////////////// //HTML: <div id="capture"> 12345 Test My Code </div> //Javascript html2canvas([login to view URL]("#capture")).then( canvas => { var image = [login to view URL]("image/png").replace("data:image/png;base64,", ""); // [login to view URL](image); [login to view URL]({ 'type': 'INVOICE', 'url': '[login to view URL]', 'file_content': image }); }); ////////////////////////////////////////////// The code seem to work but I get the printed output with wrong proportions are not correct in the printed outcome. Same results in all printers including print to PDF.
