Zoho Backstage + SUNMI V2s Plus: Portable Badge Printing and Check-In

Check-In and Badge Printing Using SUNMI Handhelds

Overview

Zoho Backstage now supports integration with SUNMI Smart Mobile Terminals, offering event organizers a seamless and portable solution for attendee check-in and badge printing.


Why use SUNMI?

Carrying separate printers to events and maintaining them can be inconvenient. SUNMI V2s Plus solves this by combining a check-in device and a thermal label printer into one compact, portable unit. These devices are easy to carry, require no dedicated setup space, and support both transparent and opaque labels.

Frequently Asked Questions 

1.  How do I set up my SUNMI V2s for label printing?
  1. Navigate to Settings > SunmiPrinter > Sunmi Inner Printer > Printer Type and choose Label Printer. Ensure that the loaded print media matches the selected print type to avoid quality issues.
