Word List Author Note: This is how Dr. B and Mrs. B sign PRINTER, but it's not shown on line this way. Most sources say to sign PRINT, and it also stands for PRINTER. (What?!?!) Know the sign MACHINE, which also is used for ENGINE and MOTOR. However, do not start with the hands so far apart (as shown on S.S.)! Just interlock the fingers (fingertips must point in toward you), and move up and down at the wrists.
