Since this printer is discontinued and a formal official driver has not been created by HP yet, you’ll want to download the latest printing solution for Windows XP.  From there, you’ll want to download the “HP LaserJet 1000 Printing Software Solution” item (when you click the download button, the filename of the download should be lj1488en.exe.

Once you download this file, you’ll want to extract the files from the archive (the file you download is an archive file).  Afterwards, find the files you extracted (i.e. c:/lj1488/) and right click on the setup.exe file, selecting “Properties”.  From there, click on the Compatibility tab, check the “Run this program in compatibility mode for” checkbox and select “Windows XP (Service Pack 3).  Click OK and run that file.  You may get a few error box windows and you may have to click on the “Skip” button when it asks you to power your printer or connect the USB cord but it should install the driver and the printer solution software.

Its that easy — the trick is to run the setup file in compatibility mode.  The same trick works for installing on Windows Vista.
