Printing
Some applications e.g. event check-in may want to programatically print without going through the browser dialog.
We expose two methods to your app's window:
window.todesktop.contents.getPrinters() to get the device's saved printers and window.todesktop.contents.print() to do the actual printing.If you have used Electron before, these methods will look familiar as we use the same function signatures.
window.todesktop.contents.print([options], [callback])window.todesktop.contents.print(
{
/*
Skips the browser print dialog and begins printing.
Boolean. Optional. Defaults to false.
*/
silent: true,
/*
Print the background color and image of the page.
Boolean. Optional. Defaults to false.
*/
printBackground: false,
/*
Set the printer to use. You can get the available
printer names with window.todesktop.contents.getPrinters()
String. Optional. Defaults to ''.
*/
deviceName: 'EPSON_WF_7610_Series'
},
/*
success will be a boolean indicating whether or not
the printing call was successful.
*/
success =>
success
? console.log('Printed successfully.')
: console.error('Could not print the page.')
);
window.todesktop.contents.getPrinters() will return an array of available printers.const printers = window.todesktop.contents.getPrinters();
console.log(printers[0]);
