ABSTRACT:
In order to indicate more distinctly the results of transverse and longitudinal adjustments of a print image, in a printer image position indicating device, a standard print position indication mark showing a printing master being positioned at the standard position relative to a print sheet and a biased print position indication mark showing a biased position of the printing master in either or both of the transverse and longitudinal directions relative to the standard position are expressed as marks each including at least two straight lines perpendicular to one another, and the biased print position indication mark is biased in the transverse and/or longitudinal directions according to a corresponding biasing of the printing master relative to the print sheet. The standard print position mark and the biased print position mark are expressed by different kinds of lines so as to clearly contrast one against the other. In addition, the biased print position indication mark is biased at a greater rate than a ratio of a biasing amount of the printing master from the standard position to the site of the printing master.
