core: Samsung SyncThru Printer doesn’t reconnect printer

The problem

The Samsung SyncThru Printer integration doesn’t properly reconnect with my Samsung C48x Series printer. This happens when this printer gets power cycled while home assistant remains running. It gets in a connect/disconnect cycle (see log below). Reload of the integration is needed to fix the issue.

2021.12.6

What was the last working version of Home Assistant Core?

No response

What type of installation are you running?

Additional information

The printer Itself is working normally. It is only the integration that doesn’t reconnect properly.
