One need not only large read the manual, but can equally start by intuitively. The QWERTY keyboard keys are a good size and have a good pressure point.
The unit is supplied in addition to the battery, the power supply, PC cable and software in a high-quality chicken suitcase where you can always put everything together in one place and take it. Also available within the scope of delivery 2 Label tapes for free.
The Dymo prints on D1 tapes of widths 6.9 and 12 mm wide, has a 2-line display, 6 font sizes, text styles 6, 9 frames, underline, and 220 special characters, symbols and clipart. 9 label templates most commonly used can be saved.
Using USB cable you can connect to your PC and DYMO then has an even greater opportunity, symbols and graphics to print.
If the battery should be empty, you can continue to work directly with the power supply while the battery recharges.
So I would recommend this unit highly enough and would not easily give up :-)
