Office 2007 printing very slow

I have 2 new Windows XP por machines with office 2007 on them. Whenevery they try to print to a printer on the network however it can take up to 5 minutes for the print dialog box to come up. One is trying to print to a printer on the back of a 98 machine and another to a networked photocopier. All now office 2007 machines work fine.

Is there a fix for this problem?
