Smith,
That's a good place to start, we can iterate on the name/syntax in the bug.

As per PWG 5100.20-2020 Section 8.1, HP Inc. has filed Issue #68 (https://github.com/istopwg/ippeveselfcert/issues/68) to report the underlying issue, which does cause an unavoidable race condition. Although the models in question have not been released yet and I cannot provide the model names, they won't be released until after July 1, 2021 transition date so we need to figure out how to deal with this before it is too late.

These printers treat the PWG Raster document format used in the v1.1 tests as a streaming document format. With streaming document formats, the Printer will flow control the TCP connection over which the Document Creation request is being made if any issues such as 'media-needed' prevent processing.

For Test I-20.1 to pass, the media has to remain removed for the duration of I-20 to allow test I-20.1 to examine the Printer's "printer-state-reasons" Printer Description attribute using a Get-Printer-Attributes operation. This produces a deadlock in the current test suite. If the document format used to perform the test was JPEG, the test would pass because the Printer does not treat JPEG JFIF as a streaming document format.
