Title: High-density printing method of printer
Inventor: KAWAGUCHI HIROMI
IPC: B41J2/485
Filed: 1993-03-05
Abstract: PURPOSE:To print with high resolution without raining the printing resolution of a printer itself by shifting and printing a next path by 1/n pitch to a preceding path in the lateral direction at the printing time in the lateral direction. CONSTITUTION:An image data of high resolution is divided and transferred to a low-resolution printer 3 by (n) times. When the printer 3 receives image data of n times the resolution, the printer thins the data by the amount of the resolution thereof before printing, changes lines by 1/n pitch, thereby sequentially conducting printing (n) times. At this time, the printing direction of a path, namely, lateral direction of the path is shifted every 1/n pitch to that of the precedent path. In other words, (n) times the resolution is allowed for the printer of low resolution only when lines are to be changed. When the image data of (n) times the resolution is to be transferred, the image data is divided to (n) transfer paths and sequentially printed while the lines are minutely shifted at the side of the printer. Accordingly, printing with high resolution is achieved.
