As I read
this page, I find

NOTE: Certain Model Script files are shipped with HP Jetadmin software. These files can be found with the HP Jetadmin software or downloaded with the HP Jetadmin software (see the HP contact information below). For printers under HP-UX, Sun Solaris, and Sun OS that are connected with HP Jetdirect, see the HP contact information below.
If I understand that, and I do find it confusing, the software should have come with your printer. If you don't have it, you need to contact HP.
I notice that page also has downloadable manuals. I would study the printer's documentation for more info.
