Lol, I didn't know what the forget the printer was or the print bricks were at all for at least a week (Or even how to change tools or paint :O). Anyways, press B to go into the brick menu and get any type of print brick. Hit Q and use scroll to go down to Printer, then use on the brick. There are two ways to choose a letter: Press the letter on the keyboard, or go into the letter section of the print menu and click the print you want. If you want a decal, then go into the Prints section and click the one you want.
