Take these steps if you're unable to certify hardware before contacting the hardware vendor.
- Try a different model device from the same vendor to test for model-specific variations. For example, a scanner may connect to Star printers but not to Epson, or it might connect to the TM-T88VI model but not the TM-T88V
- Experiment with different connection modes. It's possible that issues are confined to one interface, such as Bluetooth, while the IP interface functions without problems.
Testing all the above combinations provides sufficient data to escalate the issue to our vendors for further assistance. Always include your Salesforce Account Executive in your communications with vendors to ensure all relevant details are conveyed.
