Office supply or craft stores like Michaels sell sheets of letters that are stickers, and they also sell rub on transfer letters. There is a very wide variety available. If you need 3D letters, refrigerator magnets are available. Any printed advertising packaging can be used. There are lettering stencils in many sizes that you use a pencil to spell out the words and then use sharpie markers in any color to finish the sign. I think you can try any of these methods if you want to get away from using a computer and printer.
