Hi,
1) suggestion: design, preview and print labels using the Windows driver. This is the efficient way. Label design with WINDEV is possible. We did it and it's working, even colors and images can be included. I doubt that a preview using ZPL is available from Zebra. Most times, hardware companies are underperformers in regards to software.
2) We know that Zebra printers do not work well if connected by USB. Connection by Ethernet works just fine.
Kind regards,
