Abstract
A system for producing output print-dot data suitable for hard copy printing devices (10). A first framestore (11) stores first intensity-related pixel data at a first resolution, which is converted to first higher resolution print-dot data by a print-dot generator (17,18). A control store (19) stores one-bit control data at the said higher resolution and the output print data is selected from the first print-dot data or from a second source of print dot data in response to the control data. Both sources of print-dot data may be derived from intensity related pixel data generated on an electronic graphic system such as a PAINTBOX (Registered Trade Mark). The high resolution data may also be generated by the system and displayed electronically with full color graphics.
