![]() ![]() ![]() ![]() For channel types that do not specify a prtChannelInformation value, its value shall be null (0 length). The description of each PrtChannelType enum value for which prtChannelInformation is defined specifies the appropriate encoding and interpretation, including interaction with other objects. The encoding and interpretation of the prtChannelInformation object is specific to channel type. prtChannelInformation is not intended to provide a general channel description, nor to provide information that is available once the channel is in use. An application capable of using a specific PrtChannelType should be able to use the combined information from the prtChannelInformation and other channel and interface group objects to 'bootstrap' its use of the channel. NOTE: The above description has been modified from RFC 1759 for clarification.Īuxiliary information to allow a printing application to use the channel for data submission to the printer. The following are examples of actions that would cause the prtGeneralConfigChanges object to be incremented: - Adding an output bin - Changing the media in a sensing input tray - Changing the value of prtInputMediaType Note that the prtGeneralConfigChanges counter would not be incremented when an input tray is temporarily removed to load additional paper or when the level of an input device changes. At this point, the management application should flush any configuration information cached about this device and fetch new configuration information. This object should be incremented whenever the agent wishes to notify management applications that any cached configuration information for this device is to be considered 'stale'. Management applications may cache infrequently changed configuration information about sub units within the printer. ![]() Such changes will often affect the capability of the printer to service certain types of print jobs. In addition, any action that results in a row being added or deleted from any table in the Printer MIB is considered a configuration change. A configuration change is defined to be an action that results in a change to any MIB object other than those that reflect status or level, or those that act as counters or gauges. Counts configuration changes within the printer. ![]()
