Describe the feature

Is it worth grabbing the certificate chain, which seems to be returned, even for local printers?

I assume insecure TLS isn't required, just a shortcut to avoid managing certs.

The chain I get back from my printer has

1 =  Subject: CN=<DEVICE SERIAL>
  Validity: [From: Sat Mar 09 05:49:13 GMT 2024,
               To: Tue Mar 07 05:49:13 GMT 2034]
  Issuer: CN=BBL CA, O="BBL Technologies Co., Ltd", C=CN

2 =  Subject: CN=BBL CA, O="BBL Technologies Co., Ltd", C=CN
  Validity: [From: Mon Apr 04 04:42:11 BST 2022,
               To: Thu Apr 01 04:42:11 BST 2032]
  Issuer: CN=BBL CA, O="BBL Technologies Co., Ltd", C=CN
  SerialNumber: [    57515c93 05c49727 a4d689c5 9d0f642f b064e0df]

[2]: ObjectId: 2.5.29.19 Criticality=true
BasicConstraints:[
  CA:true
  PathLen: no limit
]

What device is this for?

A1 Mini
