A processor for sums the sampled pixels, so that a total pixel on count in the digitized image may be estimated. A plurality of pixels may be included in bytes in the data stream; a look-up table, random number generator or other device may be used to select the addresses of the bytes to be sampled in the byte stream. The system may include an ink metering controller for providing ink to a printer or a printer service status indicator for providing various forms of printer consumable and component service data.
