Abstract

Resource capture by an IPDS print device has traditionally been done by marking resources for capture off-line, then performing capture while printing. Disadvantages to this approach are that downloading resources to be captured or synchronization to ensure that captured resources can be activated can cause a data underrun at the printer mechanism. A data underrun can result in abrupt halts in printing (clutching) or in the generation of extraneous blank sheets. Off-line capture removes the potential for print time delays.

A Standalone Utility to Capture Data Object Resources at an IPDS Printer

    Resource capture by an IPDS print device has traditionally been done by marking resources for capture off-line, then performing capture while printing. Disadvantages to this approach are that downloading resources to be captured or synchronization to ensure that captured resources can be activated can cause a data underrun at the printer mechanism. A data underrun can result in abrupt halts in printing (clutching) or in the generation of extraneous blank sheets. Off-line capture removes the potential for print time delays.

    A standalone tool could be given a list of resources. If a resource is identified by Object Identifiers (OIDs), the resource can be activated. If a synchronization with the printer indicates successful activation, no further effort is required. If activation is not successful, or the resource is specified only by name, a filename matching the resource name must be found in the print environment search path. Any required unique identifier or time stamp will be extracted and used to activate the resource after downloading it. If the full list of resources is too much to maintain in printer memory at once, this is known before print (or even production) starts and printer capacity can be upgraded. A resident resource list can be compiled and used to generate reports on the state of captured resources at the printer. The captured resources can reasonably be expected to remain in capture memory at the printer if the only capture mechanism used is the off-line tool, and a print server such as IBM Infoprint Manager can ensure that all print hosts, such as IBM Print Services Facility (PSF), are inactive when the capture tool is executing. The state of captured resources would therefore be static during invocations of PSF. The tool could optionally leave any or all of the resources activated. This absolutely ensures that the resources remain in storage on an IPDS compliant printer. The activation status of a resource would be indicated in the resident resource list generated by t...
