[cups-devel] job-password and HP printers

I found that HP printers offer job password protection via IPP, e.g.
my LaserJet 500 M551 reports:

        hp-save-job-password-type (keyword) = alphanumeric
        job-password-supported (integer) = 12
        hp-save-job-password-min-length (integer) = 4
        hp-save-job-encryption-supported (1setOf keyword) = aes128,aes256

I used ipptool and print-job-password.test included in CUPS 2.2.2 in
order to test this. However the options are ignored and the job is
printed as if nothing was provided.

Is there anything known about this test case and HP printers?
