HP 400 Sharing

I have 2 networked PCs.
One of them have shared HP400.
After I have installed new drivers for HP400, I can’t print any document from network! Only localy! Why?

Printer is ejecting catridge and enable “Change catridge” sensor-button… and nothing to do to print. When I press button to get catridge back, it’s ejecting it back!

Any sugestions?

Thank you for your help.
Igor.
