sprint layout printing problem with hp1200 laser jet.

Hi. I am having a weird problem here. My setup is the computer running windows 7 ultimate 32bit, Hp1200 series Laser jet printer with upd-pcl6-x32-5.6.0.14430 printer drivers downloaded from Hp's official web site.Windows 7 does not have a driver for this model.
previously i have been designing circuit boards Using both EAGLE and sprint layout5 on the same computer and printer running Windows XP and there were no problems but as soon as i switched to Win7 each time i print a board designed with Sprint layout7 the print is little smaller than actually what it should be i means the pins for ic,s headers etc won't fit.The pads are printed a little closer than what they should be.I designed some TQFP44 to DIP44 adapter and after making the board the header pins wont go in straight because there is less space between the pads this was not a problem under windows XP.
Can any one come up with a solution for this problem.
Thank you very much.

Measure the scaling error, apply a correction factor.

Thank you FVM.
It worked.In calibration i changed the horizontal correction factor from 1.00000 to 1.01010 and now the prints are exactly what they should be.
