I basically map a network drive to the location (i.e. turn http://it-etp.xyzcorp.com/sites/abcdept/ to \it-etp.xyzcorp.com\sites\abcdept\, browse to it, and map a drive to the location (mapping a drive is optional, but helpful in SharePoint management in the long run). There are many ways to perform the next steps, but basically I open my "Printers and Faxes" and open the destination printer I want. I then open the browser that I mapped the SharePoint site in, select the files, and then drag / drop them onto the printer. You will likely get a message letting you know that you will be printing multiple documents, but I disregard those and let the system work away (it may take quite a while depending on the number of docs you wish to print).
