Note for Windows users:

The 'scan' command relies on the Bonjour service. Check whether Bonjour is

installed (Control Panel > Programs and Features). If not, you can download
|
|
Bonjour for Windows (included with Bonjour Print Services) from here:
|
|
https://support.apple.com/kb/DL999
|
|
|
|
After installing Bonjour, restart your PC and run the 'balena scan' command
|
|
again.
