A method triggers a printer () to receive a signal () from a print engine () indicating the initiation of the transmission of print data; transmits a shorter signal () to a printer ASIC (), in response to receiving a first signal; receives a first line of data to be printed from the printer ASIC (); receives a second signal from the print engine (); transmits a second shorter signal to the printer ASIC (), in response to receiving a signal; receives a second line of data to be printed from the printer ASIC (); and transmits the first line of data to the print engine (). This allows a slower printer ASIC () to be used with a faster print engine ().

Bandwidth booster for aging printer ASICs

A page generation system that efficiently generates a page segment by clearing memory immediately after data representing the page segment is read from memory. The system generates a page in memory by writing the data representing the image content of the page to a memory block. The memory block is initially clear (all logical 0's) to enable the system to efficiently generate the page segment by writing the positive content of the page segment without having to write the blank sections of the page segment. By clearing memory immediately after data is read from memory, the page generator does not need to zero clear a memory block prior to constructing a page segment therein.
