In other words
Divide each pixel dimension by the DPI as hglucky demonstrated.
High quality printing needs 300 DPI. You probably won't actually need that high a screen number.
Most desktops will print fine with 220 - 250 DPI.
Some very large format printers will print with as little as 38 DPI.
If you are printing at a service bureau ask them what DPI tolerances their machine can handle. A lot of people just say 300 but press them and ask what you can get away with.
For a desktop printer contact the customer service department of your printer brand and ask them the preferred dpi range for your model.
