How to fix this error?

Please check whether the page format specified in the form used to
print out your document is also maintained in table TSP0A. The page
format (page size and page orientation) can be specified in absolute
units of measurement (such as centimeters or inches) or in
lines/characters.
The page format for line printers with continuous forms should always
be specified in lines/characters, as the form feed and horizontal
positioning is carried out with line feeds and blanks.
If lines/columns are used, the line and character number selected must
correspond to the CPI and LPI values used in the form's header data,
otherwise the printer driver cannot calculate the paper size correctly.
Example: The paper format used in the form is defined in table TSP08 as
132 characters and 72 lines, and LPI=6 and CPI=10 are specified in the
form as well. 72 lines exactly should therefore fit on the paper used
where the line feed is 6 lines per inch (6 LPI), and 132 characters (at
least) should fit into a printed line where the font for printing is 10
characters per inch (10 CPI).
