Abstract: An improved printer controller system includes bitmap buffers for storing bitmaps as uncompressed data and a buffer manager for managing an allocation of the bitmap buffers to the bitmaps. The buffer manager is configured to recap one of the bitmap buffers according to a bitmap identifier associated with a requested bitmap. A method for managing buffer allocation in a printer apparatus includes allocating one or more buffers to a bitmap, assigning a bitmap identifier to the one or more buffers, and printing the stored bitmap. The method further includes releasing the one or more buffers, receiving a request including the bitmap identifier, and reallocating the one or more buffers to the stored bitmap.

Abstract: An image forming apparatus includes a sheet feeding cassette, transport rollers, a pick-up roller, a sheet detector, and a control section. The sheet feeding cassette stores sheets for developer images to be transferred thereonto at a secondary transfer position. The transport rollers transport a sheet at variable speeds along a sheet transport path which extends from the cassette to the secondary transfer position. The pick-up roller feeds a sheet into the sheet transport path. The sheet detector detects whether a sheet is fed from the cassette. When the detector detects that a sheet is not fed, the control section controls the pick-up roller to feed the sheet again. The control section varies respective transport speeds of the pick-up roller, a sheet feed roller, and the transport rollers, according to number of attempts to feed the sheet.

Alternatively, the stored image of the document may be examined to determine whether it includes selected information. If the stored image of the document includes the selected information, producing any copies of the document is withheld unless it is determined that the document has been removed from the document copier.
