Carrying Strap
Refer to Figures 19 and 19a. There are two varieties of carrying strap. One of them clips onto the printer’s “D” rings as does the shoulder strap, and the other is secured to the printer permanently with loops in the strap secured by sleeves captured between the printer’s upper and lower covers.
Either strap provides the user with a convenient and secure method of carrying the printer.
