The forum is not a direct way to contact HP Support. If you are looking for an immediate response then please contact HP on thier 1-800 number.
That being said what you have described here sounds like a networking problem. You should bring this to the attention of whoever is the administrator of your network to have them troubleshoot and resolve.
If you would like assistance from forum members like myself then please atleast provide us with the HP Printer models you are working with.
