Problem Statement

The first standards-track definition of the "printer-state-reasons" attribute of the IPP Printer object was published in IPP/1.1 (RFC 2911). Subsequent IETF and PWG IPP extensions have defined additional values for "printer-state-reasons". But the mapping of printer device and printer subunit alerts defined in the 'PrtAlertCodeTC' textual convention in IANA Printer MIB (originally published in RFC 3805) is very sparse.

When deploying printers in enterprise networks, customers often disable SNMPv1 (RFC 1157), based on local security policy - alternative secure SNMPv3 (RFC 3414) is not widely supported by current printers. In order to manage, provision, and service these network printers, there is a clear customer requirement to support secure queries for device alerts. IPP/1.1 (RFC 2911) can be securely deployed in enterprise networks, using TLS/1.0 (RFC 2246) and HTTP/1.1 Upgrade (RFC 2817), to fulfill this customer requirement.
