Data that should be printed on the same page is printed on two separate pages

Cause 1

The application software's "Line spacing" and "Number of lines on a page"
settings are not correct.

Change the settings so that the data fits on one page and print the data again.
(See the application software manual.)

The Timeout setting is too short, when the Personality setting is set to 'Auto'.

Remedy

Change the Personality setting to a setting other than 'Auto', or increase the
Timeout setting. (See "Personality," on p. 2-22, and "Timeout," on p. 2-15.)

Perform an Automatic Gradation Adjustment. (See Chapter 4, "Customizing
