Hasmorepages property fails - vb.net

Question

I have created a routine that is intended to print a variable number of lines and/or pages, based on a queue of line information previously stored. Each page prints fine, but when printing more than one page, two pages overprint. I can't see my logic error, but there must be one. A copy of the offending code is follows. Nextline.newpage is a boolean set to true to force a new page. In my text example there were six "Newpage" and "hasmorepages" was set to true six times, and the routine was exited six times. Still the output was four pages with one printing correctly, and three with two pages printed on one sheet. Any help would be greatly appreciated. By the way, this is my first question, so be kind.

Dim LineBackColor As String = Nextline.backColor
