Hello,
Usually, when you're printing a document, it's the "white space" at the margins of your page that make it look good. The margins create a sort of frame for your words, increasing the document's visual appeal. For some specific purposes, though, like a photo or a full-page graphic that will become a brochure, you'll need to print a full page from edge to edge. Each program has its own settings to do this, but they're pretty similar.
Setting Margins in Photoshop Photoshop is typically used by graphics professionals, so it has more – and more complicated! – print settings than most programs. Most of them are related to image quality and resolution, so you don't need to deal with them in this instance. Start by choosing "File" and then "Print," and clicking the "Position and Size" settings. Usually, the default option is "Scale to Fit Media," which prints to the page margins. Deselect it, then manually enter scale, height and width values that equal the full size of your paper. Click "Print" to print your image. This should work for any low-volume printing you do in-house, but if you're preparing an image as "camera-ready" art for an outside printer, it's generally best to print on paper that's larger than your final image, so your printer can work with crop lines for alignment purposes.
