I'm not a gimp expert, but some of what I say here may work for you.

The following applies to gimp 1.2.1, but it may be relevant to older versions.

Gimp provides onscreen rulers and guides. If you want the rulers scaled in 
inches, click "File - Preferences - interface - image windows". Unclick "Use 
dot for dot". Click "Show rulers".

If you want to calibrate gimp to more closely match your monitor settings, 
click "File - New File - monitor". Click "manually", select "pixels/inch", 
then click "calibrate". You will see two rulers on the screen that you then 
measure with a handheld measuring device.

These configuration changes seem to apply only to new windows.

Print through gimp's print dialog, rather than from the command line. The 
print dialog contains a print-scaling feature. With it, you can resize the 
image for printing without necessarily affecting the saved image. When I 
tried it, an image that gimp claimed would print at five inches wide 
accurately printed five inches wide on my officejet 600.

You probably should test your settings before starting a big project.
