We've created these Small Business Starter Packs to streamline your business using Zebra products. The Starter Packs are made up of: 
ZD421 - 4-inch desktop printer. 
Standard shipping labels measuring 102mm x 152mm - these are direct thermal labels (designed for short term use) that do not require the use a thermal transfer ribbon. 

• Direct thermal printing produces sharp, quality labels with good scannability.
• Direct thermal is ideal for applications requiring only a short shelf life — meaning the label image does not need to last very long. Shipping labels and receipts are ideal applications, for instance, while product labels are not.
• Direct thermal printers are simple to operate compared to most other print technologies because there is no ink, toner or ribbon to monitor or replenish.
• With no supplies to replace other than the material to be printed, long-term maintenance costs remain low.

For product identification labels or other labels that require having a long shelf life we'd recommend instead using thermal transfer labels alongside a thermal transfer printer and thermal transfer ribbons.
