There is a cool utility available from LinuxPrinting.org that can help align your margins. Below is how we configured our HP Laserjet 1200:

This way you get well-centered printouts and you can make use of the whole imageable area of your printer, The driver settings are overridden when this adjustment is used. This is especially important when your printer is used with a driver for another printer to which yours is compatible (for example many laser printers are compatible to the HP LaserJet printers). Your printer prints with this driver, but the non-printable margins are usually different or the contents is even not centered. With this program you can fix these problems The program can only be applied to local printer queues. The following queues are available: 1 Each 2 One 3 sample 4 hp-laserjet-1200-1 Please enter the number of the desired printer and make sure that it is connected to your computer and turned on. Number: 4 Printing margin/offset adjustment page ... Please read the instructions on the margin adjustment page and determine the six numbers mentioned there. If you measure in cm and not in inches, devide the measured quantities by 2.54 before you insert them into the equations shown on the page. You do not need to create any file with PostScript commands, this program will insert your settings into your printer's configuration. If the adjustment page did not come out of your printer, this method cannot be applied, press Ctrl + C to stop this program. This can especially happen with very old PostScript printers. Note also that this adjustment does not necessarily work with every driver. The concept is taken from GhostScript and the implementation of this program is not much tested yet.

You really do need to get out a ruler and measure for H and V. The instructions are on the page that is printed out.
