Errors in Console.log when using OfficeJet 6210

Question

Just ended a long, frustrating attempt to get support from HP regarding errors that appear in the console.log when scanning to PDF. They claim it's not their software -- The tech actually claimed that their software was thoroughly tested, ships bug-free and that it's 100% an Apple issue.
Here's what gets spewed into console.log:

Answer 1

Unsurprisingly, Apple confirmed that this was a HP error and that they would contact HP.
I tried to pass-on the info to HP, but I received the response, "Console.log is not an HP application. You will have to contact the vendor of Console.log and inform them of the error."
