WIA_IPS_SCAN_AHEAD_CAPACITY

The WIA_IPS_SCAN_AHEAD_CAPACITY describes the maximum number of pages that the scanner can scan ahead (and store in the internal scanner memory buffer) at the current scan job settings (the current document size, scan resolution, data type, file format, compression, and so on). The WIA minidriver creates and maintains this property.

Remarks
