Designed for installers, electricians and tradesmen but economical enough for homeowners and DIY folks who might only use it occasionally. Prints labels up to 3/4" wide in several colors, and also directly onto heat shrink tubing. Fits nicely in the hand, with a very user-friendly keyboard and several special features. A "Favorites" key gives you single-key access to your most commonly-used symbols and labels. A "Custom" key allows you to customize the tool so you minimize keystrokes.
