Help Creating Vista "Print Test Page" Script

I am not a script writer. In fact, the last time I wrote a script it was by creating a .bat file to run on an old MS-DOS 5 machine. But I sure would appreciate help with instructions on setting up a printer script for the printers on my Vista home network.

I have four PC's, 3-Inkjets and 1-Laser printer on my network. To keep the inkjet ink cartridges from drying up from non-use, I'd like to setup a routine on one of the Vista PC's to automatically issue a "Print Test Page" command to each of the inkjet printers once every week. Can this be done, and if so, how?

Thanks in advance for your assiatance...

Either I posted this at the wrong website/forum, or perhaps what I am trying to do cannot be done in Vista. Would appreciate some direction from an administrator or one of you scripting experts, please.
