Abstract
A printer 10 stores print image data in memory 56 as the print image data is used by a print engine 12 to print an image in accordance with the print image data. In one embodiment, separate data buses (17, 46) and separate processors (40, 50) are used to transfer the print image data to the print engine and the memory so that the transfer operations can occur independently and in parallel. In another aspect, the print image data is compressed before it is stored in the memory. In yet another aspect, an overrun condition is detected when the transfer of data to the memory falls behind the transfer of data to the print engine. During the overrun condition, transfer of data to the memory is suspended until after the page has been printed.
