Abstract
The print preview screen has a button enabling the operator to select the direction in which previewed pages are offset. The print preview screen also has a display screen enabling the operator to specify which sheet is displayed in the foreground in front of all other sheets, which sheet is displayed in the background behind all other sheets, and the offset distance between the stacked sheets. The following process is then repeated for each sheet based on these operator specifications. Data for one sheet is written to a 1-sheet display buffer (30). Data for areas not displayed is then erased from the 1-sheet display buffer (30). The data in the 1-sheet display buffer (30) is then transferred to the display data memory (40).
Claims12
An apparatus for print preview which presents printout before printing by the digital printer, comprising
- a display portion;
- a display data storage portion for storing display data representing content to be displayed on the display portion;
- a print data storage portion for storing print data to be printed by the digital printer;
- and
- a display control portion for transferring and storing print data corresponding to the printout to be displayed as the print preview from the print data storage portion to the display data storage portion, and thereby presenting the printout on the display portion;
- wherein the display control portion stores print data corresponding to a plurality of sheets of printout to the display data storage portion while offsetting the storage address for each sheet of print data;
- and
- the display portion presents printout for the plurality of sheets in parallel offset positions page by page based on data stored in the display data storage portion by the display control portion.
