Vista - Vista, HP Laserjet, Top Margin Problem

Hi,

I have just noticed that when I print a document the top margin does not
print correctly. When I print a Microsoft Word document with a top margin of
0.5 inches it actually prints with a 3/8" top margin. This also occurs if I
prints a page from IE 7 - my default top margin is 0.75 inches but the page
prints with a top margin of 5/8".

This is a new computer that I received in Dec 2007, I did not notice this
problem previously - so I cannot tell you if this is a new problem or not. I
am running Windows Home Vista Premium SP1. The printer is a HP Laserjet 2100
that is connected to the computer via an USB to IEEE-1284 Parallel printer
cable. The print driver I am using is the HP LaserJet 2100 PCL6 driver.

I have deleted the printer and then let Vista reinstall the printer when it
finds new hardware. HP does NOT have a newer driver for this configuration.
They list have a universal driver but it does not apply to printers connected
via a USB port.

I am at a loss on how to resolve this, any suggestions?
