Print form builds each printed page in memory. Each page is printed when the page in memory is full or when you call PAGE BREAK. To ensure the printing of the last page after any use of Print form, you must conclude with the PAGE BREAK command. Otherwise, if the last page is not full, it stays in memory and is not printed.

This is also true if you print only one page which doesn't fill the memory. Unless you call page break, the page may not be printed.
