print parameters on windows

Hello

I've been google'ing to try to find an answer to my question but can't seem to find it.

What I want to do is to pass the email address of a user printing from the HP-UX to a printer attached to a Windows 2003. The printing is done using lp.

I can see that the printjob on windows has some parameters. fx notify, docname etc. So I want to set one of these to hold the email address.

Do you know how to solve this or if this can be done?

Thanks
