Ok, so your just went out and bought a portable labeler. Save the receipt, you might be returning it after this snippet. I have owned roughly 5 of the self-contained labelers, they are all a waste of time. Do yourself a big favor and buy a label printer for the computer. I started with the Brother P-Touch PT-750w , though Brother has a full line up of PT labelers. Depending on your budget and needs, another product in their line might work better for you.
The Mac/PC/Smart Device compatible P-touch Editor allows you to easily control every aspect of the selected cartridge. Typefaces, symbols, drawing tools and custom graphics, allow you to quickly create a template that you can save. The downside, no file exchange from the computer to the smart device. That said, you can't beat the capabilities for the price, $105 on Amazon.
The P-Touch line of label cartridges come in so many different types. Everything from "iron on" to "wire wrap", there isn't anything you can't slap a label on. You will find and put items away faster, making labeling an important element in an efficient workflow environment.
