I think you make a good point.<br class="">
<br class="">
Smith,<br class="">
<br class="">
I think you can make a general statement about authorization, something along the lines of:<br class="">
<br class="">
"Specific authorization mechanisms are outside the scope of this document. The Internet Printing Protocol/1.1 [STD92] defines authorization roles for end users, operators, and administrators, but does not define how a Printer maps those roles to authenticated users."<br class="">

> Sorry, my confusion continues. Your new Authorization example may be valid, but it seems odd to me that someone would have an account in a printer but not have authority to print at all. Conditional authority, restricting use to certain times or restricting color, or quantity, etc. would be more realistic, but that is at the IPP level and does not appear to be addressed in this specification. <br class="">

The printer accepts these credentials, but that account is not authorized to access that printer. Harry's laptop shows a notification dialog expressing this to Harry. Harry clicks “OK” and looks for a pencil.<br class="">
