The picture must be scanned once for each color component, as the
printer can only define one color at a time. ie. If 'PCC_YMC' then
first pass sends all 'Y' info to printer, second pass sends all 'M'
info, and third pass sends all C info to printer. The CalComp
PlotMaster is an example of this type of printer.
