Printable area
Bottom margin (bottomspace)
Value and behavior
Specify the distance from the bottom edge of the printable area to the area where printing ends within the range ±30 cm using an integer or decimal with its unit appended at the end. Note that there may be some discrepancy in the actual printing.
The distance can be specified in mm, inch (1 inch = approximately 25.4 mm), pt (points) or dot (number of dots) units, unless the specified value exceeds the above-mentioned range. For example, if you want to set the bottom margin 25 mm from the bottom edge of the printable area, enter the printing option as follows:
bottomspace=25 mm
When no unit is appended at the end of the value, the machine calculates the area assuming the unit of the specified value is "cm".
Explanation
When this printing option is specified, the actual margin is calculated by adding this value and the value specified for "C. Bottom Margin" on the RTIFF Menu.
