I have a new HP Pavilion Desktop computer that I just added my new MG3620 printer to. I think it is wireless, but I installed everything using the CD installation and I am using USB cord, even though it may be running as a wireless printer. Not sure if that is making sense?</P><P>The test print worked, however, when I try printing anything off the internet like an email message, I get the following message:&nbsp; "You may be using an extension that blocks popups. To print, click OK to enable popups for the current session."</P><P>I cannot understand what an extension they are referring to and how would I prevent a popup?</P><P>&nbsp;</P> Sun, 14 Oct 2018 08:36:07 GMT jkoressel 2018-10-14T08:36:07Z https://community.usa.canon.com/t5/Desktop-Inkjet-Printers/MG3620-Unable-to-Print/m-p/256835#M23686 <P>Hello everybody.
