Abstract
A storage control system for a print image data in a print control apparatus includes a unit for generating a print image expressed by a set of a plurality of dots as a digital data having a dot carrying a two-dimensional address corresponding to a bit, an address conversion unit for converting a digital data carrying a two-dimensional address into a digital data carrying a one-dimensional address, and a full-dot memory for storing a digital data carrying a one-dimensional address in a one-dimensional address structure.
Claims5
A print image data storage system comprising:
- means for generating digital print image data representing a plurality of dots to be printed on a sheet of paper, each of the dots being represented by one bit of the digital print image data and having a two-dimensional address associated therewith, the two-dimensional address including an x-address representing an abscissa of the dot on the sheet of paper and a y-address representing an ordinate of the dot on the sheet of paper;
- a first register for designating y-addresses of the dots to be printed on the sheet of paper;
- a second register for designating x-addresses of the dots to be printed on the sheet of paper;
- a third register for designating information about the sheet of paper;
- address conversion means responsive to the first register, the second register, and the third register for converting two-dimensional addresses specified by the y-addresses designated by the first register and the x-addresses designated by the second register to one-dimensional addresses based on the y-addresses designated by the first register, the x-addresses designated by the second register, and the information about the sheet of paper designated by the third register;
- and
- a one-dimensional full-dot memory receiving the digital print image data from the digital print image data generating means and responsive to the one-dimensional addresses from the address conversion means for storing the digital input image data at the one-dimensional addresses.
