server error codes. All codes aredescribed in Sections 13.1.1 through 13.1.5 in
RFC 2911.
[50 – 68] We define the various operation IDs next. There is one ID for each task defined
by IPP (see Section 4.4.15 in RFC 2911). In our example, we will use only the
print-job operation.
[69 – 76] The attribute tags delimit the attribute groups in the IPP request and response
messages. The tag values aredefined in Section 3.5.1 of RFC 2910.
