Printing partially working

[Germaris]

Hi there!

I implemented a printing function which is working nice even for multiple pages.

Problem is as follows...
Say we have a text 100 lines long.
Each page can hold 80 lines.
We should have:
Page 1 = from line 1 to line 80
Page 2 = from line 81 to line 100

Instead, I get:
Page 1 = from line 1 to line 80
Page 2 = from line 20 to line 100 !!!
i.e. lines 20 to 80 are printed twice!

I think problem is in maxScroll but can't find the mistake...
Could you help me find it?

Many thanks in advance.

Best regards,
Gerry
