For sure, trying to do so as securely as possible. But need a printer that works with PureOS, and figure one with WiFi is not very secure.
If you're trying to print the backup over wifi, then yeah
potential security issues.
Two options, really:
- You could write the paper backup down by hand.
- Use the "secureprint" option. This would negate anyone snooping the on the paper backup over wifi. Make sure to read the instructions as you'll need to write another password on it to decrypt.
Otherwise, turn wifi off on the printer entirely and connect via the classic USB B cable.
Always test the backup too.
