Definitions

• Each downstream processor acknowledges receipt of the print data.
• the main controller communicates bidirectionally with the individual downstream processors to enable or disable the output, to configure output parameters such as printhead width and the number of pixels in the paper motion direction per encoder pulses from the paper motion encoder and ripping parameters such as maximum frame length for registration cued documents.
• the main controller also tracks the status of each frame given to the downstream processors, and detects errors from the downstream processors.
• the receiver is a paper web and the transport unit has a transport controller, a receiver supply, a receiver collector, a drive, and a plurality of support members.
• the transport controller is a programmable logic controller.
• the receiver supply is a core that holds a spool of the paper web.
• the receiver collector is a mandrel that is driven by the drive.
• the support members include a plurality of rollers positioned to bear the web. Other types of support members, such as skis and bars, could be substituted for one or more of the rollers.
• the core and one or more of the support members can also be driven.
• the receiver collector can collect the web in a roll, can use any suitable post print peripheral such as a folder or cutter, or can feed a production line for more complete finishing.
• the first printhead can print frames of a large number of documents before the first such document arrives at the last printhead.
• printheads can be divided into a first set that prints one side of the document and and a second set that prints the second side of the document, with a separation between the two sets for drying, flipping, the receiver, or the like.
• the first printhead prints a large number of documents before the first such document arrives at the last printhead, which prints on the second side of the document.
• the first printhead stops printing long before the last printhead stops printing.
• the print queues need to be large. This is particularly the case for high speed web fed presses, since a large amount of inertia is associated with moving the web through the press at high print speeds. These presses cannot quickly stop and restart the motion of the receiver.
• Different print jobs tend to have different content and, thus, different content-related printing requirements.
• Different print jobs in a stream of print jobs and different documents within each of those print jobs can have different non-image requirements.
• two or more of the print queues can contain printable frames of different documents of the print job or from different print jobs.
• the estimated maximum printing durations periodically determined are each across multiple documents, rather than representing different printable frames of the same document. Suitable periods for iterating the estimates can be determined heuristically based on printing experience with similar jobs.
• a single estimate predicting an entire print job would be undesirable, since the variable overlap of the different documents or different jobs in the print queues during printing would make such a prediction complex.
• a single estimate would also be unable to account for actual variations in time requirements during the process, such as time to recognize and apply a registration cue.
