I've got a client who has a investor presentations that I take from PowerPoint and optimize into jpegs then into a JavaScript slide show.

What I'd like to do is have a button in there that states, 'Print Current Slide' that would allow them to do just that. Problem is, the JavaScript slideshow is in a popup window and I really don't want to have another when they want to print a slide. Also, the optimized jpegs are smaller and not very good print quality.

Could I have my button dynamically select a full sized jpeg on the server and auto print that without actually showing it? So clicking on the 'Print Current Slide' button would tell the script what slide they want to print and to search it out in a directory and automatically send that to the printer?
