The optional SOP Classes address functionality beyond that of the Print Management Meta SOP Classes. One or more optional SOP Classes may be used in addition to the Print Management Meta SOP Classes.
The following functionality is supported by the optional SOP Classes:
annotation (text associated with a sheet of film)
tracking the printing of the print session
retrieval of printer configuration information
Use of these optional SOP Classes allows an SCU to provide information to be printed with or on an image without burning the information into the image pixels. If these optional SOP Classes are not supported by both the SCU and SCP, then only the information burnt in to the image pixels before they are sent to the SCP will be printed. If the optional SOP Classes are not supported, the SCU is responsible for burning all expected text or graphics into the image pixels.
The following optional SOP Classes may be used in conjunction with the Basic Print Management Meta SOP Classes specified in Section H.3.2.2.
|SOP Class Name||Reference||Usage SCU/SCP|
|Basic Annotation Box SOP Class||H.4.4||U/U|
|Print Job SOP Class||H.4.5||U/U|
|Presentation LUT SOP Class||H.4.9||U/U|
|Printer Configuration Retrieval SOP Class||H.4.11||U/U|
Note: Negotiation of the Presentation LUT SOP Class does not imply any behavior in the SCP. Behavior is explicit when the Presentation LUT SOP Class is created and referenced at either the Film Session, Film Box, or Image Box levels.
