CommentIdentifier (4 bytes): An unsigned integer that identifies this comment record as specifying public data. The value 0x43494447, which is the ASCII string "CIDG", identifies this as an EMR_COMMENT_PUBLIC record.

PublicCommentIdentifier (4 bytes): An unsigned integer that identifies the type of public comment record. This SHOULD be one of the values listed in the preceding table, which are specified in the EmrComment enumeration (section 2.1.10), unless additional public comment record types have been implemented on the print server.

PublicCommentRecordBuffer (variable, optional): An array of bytes that contains the remainder of the public comment record.

0	1	2	3	4	5	6	7	8	9	1 0	1	2	3	4	5	6	7	8	9	2 0	1	2	3	4	5	6	7	8	9	3 0	1
PublicCommentRecordParm (variable)
...
AlignmentPadding (variable, optional)
...

PublicCommentRecordParm (variable): An array of bytes that contains the parameters for the public comment record.

AlignmentPadding (variable, optional): An array of up to 3 bytes that pads the record so that its total size is a multiple of 4 bytes. This field MUST be ignored.
