Yes, that is the behaviour in GL8.1A. In GL9.0A, only pages 21 and 22 would print.

It sounds like each page is a separate statement. If they were in fact treated as separate statements (either by being on separate sheets within the same workbook or being separate files added as items to a statement group), you could either click on the sheet and print it only or open the statement group and print the desired statements separately that way.
