Config failure after printer.cfg update?

[BlakeAntonio]

I am trying to add printers to the printer.cfg. When I verify the config it fails with:
Could not find any host matching 'LaserJet 400 MFP M425dn'

Any ideas on what causes this?

Just a guess but in seems to suggest it expects a host definition for the printer. You might try creating one if there are no better ideas.
I would use a valid hostname.
