Send page to print in Chrome from console?

Question

linux

Lord, good day.

The situation is as follows:
There is a thermonuclear captcha made on a flash, where letters appear only when you hover over them with the mouse and in turn, and plus garbage constantly “falls” from above to complicate recognition ( examples ).

It suddenly turned out that if we open the flash drive in chrome in a separate window and send it to print, we will get this:



Next, we print “to the picture”, turn up the brightness, and we are left with only clean large letters that any OCR recognizes.

The only problem is chrome, which does not want to print without user intervention. Has anyone come across?

Answer 1

You can try this option.
Launch Chrome without preview.
Enabled with the --disable-print-preview option.

Answer 2

Well, calling the print window is quite simple:

document.execCommand('print', false, null);

The second parameter is just responsible for suppressing a possible UI, but, apparently, does not work for printing.
