Just like the 1131-01® but it has date coding capability. 4 of the 8 characters are for dating (month, #, #, year). The 1131® is an easy to load price marker. Pop the top, drop in a roll, snap the top down, feed the label strip in the bottom and go! In fact it's 75% faster to load this gun than many other labelers. The ink roller is even easier to load. Just snap it on the spindle and go! This is a great labeling gun for date coding items and cases. It doesn't require lot's of training to use or load and its ergonomic design cleanly fits your hand for comfortable operation.
