##### B.4.2.3.3 Association Initiation Policy

###### B.4.2.3.3.1 Activity - Film Images

###### B.4.2.3.3.1.1 Description and Sequencing of Activities

A user composes images onto film sheets and requests them to be sent to a specific hardcopy device. The user can select the desired film format and number of copies. Each print-job is forwarded to the job queue and processed individually.

The Hardcopy AE is invoked by the job control interface that is responsible for processing network tasks. The job consists of data describing the images and graphics to be printed as well as the requested layout and other parameters. The film sheet is internally processed, converted to a STANDARD/1,1 page and then the page image is sent. If no association to the printer can be established, the print-job is switched to a failed state and the user informed.

Figure B.4.2-5. Sequencing of Activity - Film Images

A typical sequence of DIMSE messages sent over an association between Hardcopy AE and a Printer is illustrated in Figure B.4.2-5:

1. Hardcopy AE opens an association with the Printer

2. N-GET on the Printer SOP Class is used to obtain current printer status information. If the Printer reports a status of FAILURE, the print-job is switched to a failed state and the user informed.

3. N-CREATE on the Film Session SOP Class creates a Film Session.

4. N-CREATE on the Presentation LUT SOP Class creates a Presentation LUT (if supported by the printer).

5. N-CREATE on the Film Box SOP Class creates a Film Box linked to the Film Session. A single Image Box will be created as the result of this operation (Hardcopy AE only uses the format STANDARD\1,1)

6. N-SET on the Image Box SOP Class transfers the contents of the film sheet to the printer. If the printer does not support the Presentation LUT SOP Class, the image data will be passed through a printer-specific correction LUT before being sent.

7. N-ACTION on the Film Box SOP Class instructs the printer to print the Film Box

8. The printer prints the requested number of film sheets

9. The Printer asynchronously reports its status via N-EVENT-REPORT notification (Printer SOP Class). The printer can send this message at any time. Hardcopy AE does not require the N-EVENT-REPORT to be sent. Hardcopy AE is capable of receiving an N-EVENT-REPORT notification at any time during an association. If the Printer reports a status of FAILURE, the print-job is switched to a failed state and the user informed.

10. N-DELETE on the Film Session SOP Class deletes the complete Film Session SOP Instance hierarchy.

11. Hardcopy AE closes the association with the Printer

Status of the print-job is reported through the job control interface. Only one job will be active at a time for each separate hardcopy device. If any Response from the remote Application contains a status other than Success or Warning, the Association is aborted and the related Job is switched to a failed state. It can be restarted any time by user interaction or, if configured, by automated retry.

Table B.4.2-35. Hardcopy Communication Failure Behavior

Exception | Behavior
--- | ---
Timeout | The Association is aborted using A-ABORT and the print-job is marked as failed. The reason is logged and the job failure is reported to the user via the job control application.

###### B.4.2.3.3.1.4 SOP Specific Conformance for the Printer SOP Class

Hardcopy AE supports the following DIMSE operations and notifications for the Printer SOP Class:

- N-GET

- N-EVENT-REPORT

Details of the supported attributes and status handling behavior are described in the following subsections.

###### B.4.2.3.3.1.4.1 Printer SOP Class Operations (N-GET)

Hardcopy AE uses the Printer SOP Class N-GET operation to obtain information about the current printer status. The attributes obtained via N-GET are listed in the Table below:

Table B.4.2-36. Printer SOP Class N-GET Request Attributes

Attribute Name | Tag | VR | Value | Presence of Value | Source
--- | --- | --- | --- | --- | ---
Printer Status | (2110,0010) | CS | Provided by Printer | ALWAYS | Printer
Printer Status Info | (2110,0020) | CS | Provided by Printer | ALWAYS | Printer

The Printer Status information is evaluated as follows:

1. If Printer status (2110,0010) is NORMAL, the print-job continues to be printed.

2. If Printer status (2110,0010) is FAILURE, the print-job is marked as failed. The contents of Printer Status Info (2110,0020) is logged and reported to the user via the job control application.

3. If Printer status (2110,0010) is WARNING, the print-job continues to be printed. The contents of Printer Status Info (2110,0020) is logged and reported to the user via the job control application.

The behavior of Hardcopy AE when encountering status codes in a N-GET response is summarized in the Table below:

Table B.4.2-37. Printer SOP Class N-GET Response Status Handling Behavior

Service Status | Further Meaning | Error Code | Behavior
--- | --- | --- | ---

Table B.4.2-38. Printer SOP Class N-EVENT-REPORT Behavior

Event Type Name | Event Type ID | Behavior
--- | --- | ---
Normal | 1 | The print-job continues to be printed.
Warning | 2 | The print-job continues to be printed. The contents of Printer Status Info (2110,0020) is logged and reported to the user via the job-control application.
Failure | 3 | The print-job is marked as failed. The contents of Printer Status Info (2110,0020) is logged and reported to the user via the job-control application.
* | * | An invalid Event Type ID will cause a status code of 0113H to be returned in a N-EVENT-REPORT response.
