Hello Richard - thanks for trying to help. I've tried both offerings from HP : lj1000hostbased-en.exe & lj488en.exe. When running either of these, there is no executable, only an .inf file. Neither one will install -7 says it is installing in compatibility for XP, but then almost at once says that the program is not compatible anyway. It is beginning to look as if:
1) it really is incompatible
2) I am an incompetent idiot.
Thanks for trying. I think I may have to bite the bullet and buy a new laser....and I've just recently bouught 2 toner cartridges ( sob....)
