I am now working to develop prototypes with IPP documents.
IBM's client sent these data to ipp server as follows.
result of analysis:
01 00 00 02 01 29 00 08 6A 6F 62 2D 6E 61 6D 65 .....)..job-name

1: IPP version 0x0100 -> IPP/1.0
2: operation number 0x0002 -> Print-Job
3: tag 0x01 -> operation-attributes-tag
4: tag 0x29 -> this tag is reserved for future integer types
5: length of attribute-name 0x0008 -> 8bytes
6: attribute-name -> "job-name"
7: length of attribute-value 0x0004 -> 4bytes
8: attribute-value -> "job1"
9: tag 0x29 -> this tag does not exist in IPP protocol specification
10: length of attribute-name 0x0016 -> 22bytes
11: attribute-name -> "ipp-attribute-fidelity"
12: length of attribute-value 0x0005 -> 5bytes
13: attribute-value -> false,
In IPP model specification, ipp-attribute-fidelity is boolean
type. And in IPP protocol specification, if 'false' then 0x00,
if 'true' then 0x01.
14: tag 0x29 -> this tag does not exist in IPP protocol specification
15: length of attribute-name 0x000D -> 13bytes
16: attribute-name -> "document-name"
17: length of attribute-value 0x0009 -> 9bytes
18: attribute-value -> "document1"
19: tag 0x02 -> job-attributes-tag
20: tag 0x15 -> this tag is reserved for future "out-of-band" values
21: length of attribute-name 0x0006 -> 6bytes
22: attribute-name -> "copies"
23: length of attribute-value 0x0001 -> 1byte
24: attribute-value -> 1
25: tag 0x15 -> this tag does not exist in IPP protocol specification
26: length of attribute-name 0x000C -> 12bytes
27: attribute-name -> "job-priority"
28: length of attribute-value 0x0001 -> 1byte
29: attribute-value -> 1
30: tag 0x03 -> data-tag
Item 4, 9, 12, 13, 14, 20, 25 are not based on IPP protocol specification.
So IBM Client can not access to ipp server.
