Hi,
It must be your printer. It worked great on my HP DeskJet 722C!

Hi
My printer is HP Laser Jet 5SiMX. It has portrait : LU L5002A2A
Landscape: LU L5002A2B.
I don't know what are those above settings. My printer has LU L5002A2A setting and 600x600 dots per inch. Could you pl. tell me what kind of settings required to get the priting properly I mean no splitting row per page.
Thanks

Just replace
double oneRowHeight=(tableView.getRowHeight()+
tableView.getRowMargin())*scale;
with

double oneRowHeight=(tableView.getRowHeight)*scale;
