I assume from your earlier response, you thought I was telling you to use the individual printer webpages?
It would appear that HP canned 32bit support. However 32Bit versions are still kicking around.
I've checked my software Repo and have found an older version with the following filename:
HP_Web_Jetadmin_10.3_-_32_bit_SW_-_build_88120_J6052-10539.exe
Because I can't be bothered to faff around with dropbox and the like, if you whack that filename into google and look for the link from ftp.psu.ac.th - This has exactly the same hash as the version I have.
