I decided to make a printing program that uses a computer to design the layout then uses a turtle and wool blocks to print it out.

How to use:

put the printer program on a computer and the start up program on a turtle.
change the id to send to on the computer and the id to receive from on the turtle
place the wool in the order it appears in the creative inventory (which is the same as the order the colors appear here. http://computercraft.info/wiki/Colors)
run the programs on the computer and turtle respectively
have fun printing
