Printing to a Zebra
Send to Zebra works when Zebra's free Browser Print app is running on this computer (download from zebra.com, search "Browser Print"). It sends to your default Zebra printer.
Otherwise use Download ZPL and send the file with Zebra Setup Utilities, or copy the ZPL into any tool that talks to the printer.
For a regular printer, choose a sheet size (Avery) or a single label size, then Print. In the print dialog set Scale 100% / Actual size and turn headers and footers off.
Preview is drawn to scale. Codes are standard symbologies, readable by any scanner or phone camera.
