### H.2.2 Print Management Service Class Structure

The Print Management Service Class Structure is shown in Figure H.2-3.

The Print Management SCU and Print Management SCP are peer DICOM Print Management Application Entities. The Application Entity of the Print Management SCP corresponds with one or more hard copy printers. If the SCP Application Entity corresponds with multiple printers then the SCP Application Entity selects for each Print Job the printer where the Print Job will be printed.

Figure H.2-3. Print Management Service Class Structure

The Print Management SCU and Print Management SCP establish an Association by using the Association Services of the OSI Upper Layer Service. During Association establishment, the DICOM Print Management Application Entities negotiate the supported SOP Classes. The negotiation procedure is defined in Section H.5.

Figure H.2-4 shows alternative configurations for printing images and image related data from one host to multiple printers.

- Configuration 1: one SCU Application Entity corresponds with the host and one SCP Application Entity corresponds with multiple printers. The SCU has no control over the print parameters of each printer and over the print destination of the Print Job.

- Configuration 2: one SCU Application Entity corresponds with the host and one Application Entity SCP corresponds with each printer. The SCU has explicit control over the print parameters of each printer and over the print destination of the Print Job. Each SCP Application Entity has one Association with the SCU Application Entity and is identified by its Application Entity title.
