IPP Operation Keywords

IPP objects support operations. An operation consists of a request and a response. When a print client communicates with an IPP object, the client issues an operation request to the URI for that object. Operation requests and responses have parameters that identify the operation. Operations also have attributes that affect the run time characteristics of the operation. These operation-specific attributes are defined as operation attributes. Print requests contain operation attributes, object attributes, and the required document data to perform the specific operation. Each request requires a response from the object. Each response indicates success or failure of the operation with a corresponding status code as a response parameter. Responses contain operation attributes, object attributes, and status messages that are generated during the operation request.

The following table describes the IPP operation keywords for the Apache Web Server Configuration.

Table A–4 IPP Operation Keywords


Value	Meaning
`All`	This keyword is used in place of an operation. The keyword is meant to signify that all operations that are supported by `mod_ipp` are selected.
`Required`	This keyword is used in place of an operation. The keyword is meant to signify that all the required operations, as defined in RFC-2911, are selected, including the following: `print-job`, `cancel-job`, `get-job-attributes`, `get-jobs`, and `get-printer-attributes`.
`Print-job`	A client wants to submit a print job with only a single document. The document data is sent with the request.
`Print-uri`	Unsupported
`Validate-job`	A client wants to validate that a print job can be handled by the scheduler before submitting a print job.
`Create-job`	A client wants to submit a print job with multiple documents. The documents are sent with the `send-document` and `send-uri` operations.
`Send-document`	A client wants to add a document to a print job that is created with the `print-job` operation. The document data is sent with the request.
`Send-uri`	Unsupported
`Cancel-job`	A client wants to cancel a print job.
`Get-job-attributes`	A client wants to gather information about a print job.
`Get-jobs`	A client wants to gather a list of print jobs in a particular print queue.
`Get-printer-attributes`	A client wants to gather information about a particular print queue.
`Hold-job`	A client wants to hold a particular print job.
`Release-job`	A client wants to release a particular print job.
`Restart-job`	A client wants to restart a particular print
`Pause-printer`	A client wants to pause (disable) a particular print queue. This operation will stop the processing of print requests in the queue. Note that the operation does not stop the queue from accepting jobs.
`Resume-printer`	A client wants to resume (enable) processing of jobs in a particular print queue.
`Purge-jobs`	A client wants to remove all jobs from a particular print queue.
`Set-printer-attributes`	Create or modify attributes of a printer.
`Set-job-attributes`	Modify attributes of an existing print job.
`Enable-printer`	Resume (accept) queueing of print jobs.
`Disable-printer`	Disable (reject) queueing of print jobs.
`cups-get-default`	Retrieve the default destination for a print service.
`cups-get-printers`	Enumerate all printers available from the print service.
`cups-get-classes`	Enumerate all classes available from the print service.
`cups-accept-jobs`	CUPS specific equivalent of Enable-printer.
`cups-reject-jobs`	CUPS specific equivalent of Disable-printer.
`cups-move-jobs`	Move jobs between queues in the same print service.
