Apple Writer: Keeping Printout‘s First Line at the Page‘s Top
If the Page Interval (PI) option of Apple Writer's Print/Program Commands doesn't reflect the exact number of lines long your paper is, the first line of each page will be printed either slightly higher or slightly lower than the first line of the previous page; if the document is long enough, the text may actually begin to spill over the page boundary.
To correct the problem, raise the value of PI if the first line printed is creeping upwards; lower it if the first line is creeping downwards.
