Title: Print control method and printer
Inventor: MORIAI SHIGETADA
IPC: B41J29/46
Filed: 2000-03-07
Abstract: PROBLEM TO BE SOLVED: To minimize waste of sheet in test print. SOLUTION: When an operator sets a test print mode, a printer contracts a document image (S1-2) and performs test print (S1-6). The operator confirms the test printed content and if no correction is required (S1-7; YES), the operator sets a normal print mode and a print control section reads out document data stored in an image memory (S1-8) and performs normal operation under conditions at the time of forming a document (S1-9). If the content of test print requires correction (S1-7; NO), the operator delivers a print stop instruction to the print control section (S1-10) and corrects the document data (S1-11). When the operator sets a normal print mode after ending correction (S1-12; YES), the print control section reads out corrected document data from the image memory (S1-13) and normal print is performed (S1-9).
