The workaround is described in the solution part of the error message. You
should reduce the column width, the column spacing, or the number of
columns until the addition of these plus the default margins is less than
the width of your paper.
For example, if Access defines the left margin at .263 inches and the right margin at .266 inches, then you have used:
.263 + .266 = .529 inches of the total 8.5 inches.
If you then define the column width at 3.8 inches, the column spacing at
.15 inches, and column count at 2, you are now under the 8.5-inches width
limit.
2 x 3.8 inches = 7.6 inches
7.6 inches + .529 inches + .15 inches = 8.279 inches.
If all these components add up to less than the page width, you can print
the report without an error.
