Stating the obvious, different printers offer different capabilities. You may have a black-and-white laser printer for basic document printouts and image proofing, and a color printer for sales documents and final image printouts. You need to select the printer to use to print the current image from among those installed on your system, as described here. Once you’ve selected the printer, you can set available page setup options, which will vary depending on the capabilities of the printer. For example, the software with many printers now calculates margins for you, so the margin choices may be disabled in the Page Setup dialog box.
