Printing from SharePoint Online

[FWBD]

Does anyone have any experience in setting up SharePoint libraries with a custom button to be able to print from the browser?

 

To put this in more context we have users who would like to print off images, Photoshop files and multiple documents from SharePoint Online without having to do them individually or have to sync them locally to do so. I've seen on sites about creating custom actions to print and create print buttons but a lot of these are old blogs and only print out the entire web page.

 

Thanks in advance for any suggestions!
