Printing in Chrome is loading preview forever [closed]

Question

On my website, printing has stopped work with Google Chrome (version 81 on Linux, if that matters). The print preview window is stuck with showing "Loading preview...".

While doing this, Chrome prints the following message on the console:

[30378:30378:0424/004907.441044:ERROR:CONSOLE(2990)] "Uncaught TypeError: Cannot read property 'marginTop' of null", source: chrome://print/print_preview.js (2990)

When I open the developer tools and set the CSS media type emulation to "print", the page is shown correctly as it would be printed, and there are no errors in the console.

How can I find out where the problem comes from and how to fix it?

Answer 1

Resetting Chrome did not solved the issue in my case, I had to disable the Print Preview by adding a key in Windows registry.

As written in Pupuweb.com

Previously this print preview loading problem was able to resolve by disabling it in chrome://flags/#enable-cloud-printer-handler. However, enable-cloud-printer-handler, however it was removed in Google Chrome Version 84.

So to disable the Print Preview feature I had to add at HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome a DWORD value named DisablePrintPreview with data 1, restart the machine and could start print again.

If you don't have the GPO Templates for Chrome you can create the keys manually or with the following line.

reg add HKLM\SOFTWARE\Policies\Google\Chrome

To add the value in command line, run as administrator the following line.

reg add HKLM\SOFTWARE\Policies\Google\Chrome /v DisablePrintPreview /t REG_DWORD /d 1 /f

Create a registry file ".reg" and add the following, run as administrator.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome]
@=""
"DisablePrintPreview"=dword:00000001
