Question : Problem: HP Laserjet 4 gives error after install to win xp w/sp 2

I have a laserjet 4 that I have install on a winxp OS with sp2. When I printer a test page I get error

 "W2 INVALID PERS".

I browsed the web and found a definition of:

The job was not printed because the requested personality, such as PostScript (MP), was not installed. Install the language in which the files are sent, together with enough memory to support that language. Clear message by pressing SHIFT and Continue on the printer.

but I'm not sure what to do. How do I  install a language?
