Abstract: A scanner-printer of the type that scans and prints in blocks, each block consisting of a preset number of image lines, in which the block of lines (SLn-2 to SLn+2) scanned by the scanning array is larger than the block of lines (SLn) printed by a printing array so that there are provided additional image scan lines before and after each block of image lines printed, the additional image scan lines providing image context data for use in processing image signals adjacent the boundaries between blocks of image lines.
