Abstract

In an external print controller added to an MFP, bit map data obtained by analyzing and developing received PDL data is once compressed and, subsequently, transferred via a PCI bus. In the compressed bit map data, the data in a compressed state is stored onto an HD in the MFP as it is. The compressed bit map data is read out from the HD, decompressed, and sent to a printer unit.
