摘要:
A system architecture is provided for a fixed-head mailpiece printer (106). The printer includes at least two laterally and longitudinally-spaced print heads (114) for depositing ink on a face surface of a mailpiece. The print system architecture includes print application software (110) or software program code operative to render print image data into a plurality of logical rectangular bitmap print buffers. Further, a field programmable gate array (FPGA) (112) remaps each of the logical rectangular bitmap print buffers into one of the print heads based upon its spatial position relative to the mailpiece. Furthermore, the FPGA (112) is operative to control the deposition of ink from the print heads (114) based upon the print image data contained in the print buffers. Moreover, the FPGA (112) minimizes processing time associated with print image rendering to achieve enhanced print system throughput.
摘要:
Apparatus and method for printing in which print software (106) is decoupled from print data (116) such that print image data can change without impacting software (106). The decoupling can be performed using distributed architecture. Additionally, tables are used to decouple the print software from the print data.

The apparatus comprises: a first module including a universal key; a second module including a unique identifier and a unique key wherein the unique key is derived from the unique identifier and the universal key and incorporated into the second module during manufacture of the second module. The second module is in communication with the first module. The apparatus further comprises a controller for performing the following subsequent to manufacture of the first module and the second module: initiating a communication session between the first module and the second module; transmitting the unique identifier from the second module to the first module; and deriving the unique key in the first module using the unique identifier and the universal key. A method for synchronization of cryptographic keys between modules of a distributed system and a method of manufacturing a postage evidencing system are also provided.

A postage printing system (100) includes a printer (160) and a postage meter (120). The printer (160) includes a memory (164), a print device (166) for printing a postal indicia and a controller in operative communication with the printer memory (164) and the print device (166). The postage meter (120) includes a memory (132, 142)and is physically separable from and in operative communication with the printer (120). The printer controller (162) detects a fault condition, stores a record of the fault condition in a history file within the printer memory (164) and, following a successful mutual authentication between the printer (160) and the postage meter (120), uploads the history file from the printer memory (164) to the postage meter memory for subsequent reporting to a data center (50).
摘要:
A method of controlling a feed rate of a printer (15), and a printer employing same, wherein the printer (15) includes a feeder motor (50) driving a feeder mechanism (55) and a transport motor (40) driving a transport mechanism (45). The method includes receiving image data for a first item of print media in a print job, processing the image data to create printable image data, and determining an image preparation time that is a time difference between the time when the printable image data is completed and the time when the start of the image data is first received. The method then further includes determining a current feeder speed based on at least the image preparation time. Following that that determination, the method includes: (i) turning the transport motor (40) on, and (ii) setting a speed of the feeder motor (50) equal to the current feeder speed and thereafter turning the feeder motor (50) on.
摘要:
A method of synchronizing the feeding and printing of sheets of media, i.e., paper, envelopes, post cards, etc. even though shingled feeds have occurred in the system. The foregoing is accomplished by utilizing two sensors (13,14) and counters to monitor two sheets of paper to allow two software tasks to stay in synchronization and release the appropriate print data to the printer (30) even when a sheet of paper was not detected in the feeder appears at the print head. The feeder sensor (13) has a counter for its Lead Edge as does the Start of Print Sensor (14) that is in the system's transport paper path. The feeder sensor counter and the start of print counter are incremented and decremented as the paper approaches the sensor and leaves the sensor. If the lead edge counter of the feeder sensor goes negative, then the feeder has shingled and the data for that sheet of paper must be printed.
