Hallo there!i am using "addthis" layers for my items but i have a problem with the printing. Although it is working it doesn`t load the k2.print.css but it takes css from chrome.How can i change that??
Thank you

Check through your browser inspector and see if it places any specific class in the body of the print window.
Then just take that class and add the css provided through k2.print.css and add it for this class as well. You will probably have to add this to your template's css file and also try to include the above classes to a print media query.
