Abstract:
A method for providing page synchronization in a color print system having a print adapter for interfacing rasterized print job data of a print job received at an input to a printer with a marking engine of the print system, comprising the steps of:processing rasterized print job data through a FIFO in the print adapter on a page basis, such that the FIFO can contain all planes of the rasterized data in a multi-plane color page; generate a status signal after each plane of the multi-plane page is printed, as an end-of-plane signal; examining the contents of the FIFO for the presence of print job data relating to a given plane printed if an end-of-plane signal for the given plane is detected during the processing of rasterized print job data; generating an error signal if the FIFO contains rasterized print job data for the given plane after the end-of-plane signal is generated; outputting the end-of-plane signal from the print adapter with no error signal if the FIFO contained no print job data during the examining step for the given plane; and repeating the preceding steps for each plane in each page until the print job is complete.
