Abstract
A word processing system is provided with separate data structures in system memory (4). One of these, the internal image array, stores data representative of alphanumeric data and low resolution graphic data in the form of alphanumeric character data and graphic character data. Another stores data representative of high resolution printed graphics in the form of a bit array. The data from the internal image array is applied to the display terminal of the word processing system to provide a representation of the graphic data with the alphanumeric data. The alphanumeric data only from the internal image array is merged with the high resolution graphic data in the bit array to produce the printer data stream for the printer of the word processing system.
