Wp Wordpress

I have a feling that this might be a fairly common problem; but new to me. I have a shared Epson Color Stylus R300 printer on a a wireless network. It is accessed by a MacbookPro (10.5.5) & iMac (10.4.11). Wireless printing works perfectly. from both Macs.

The problem is that I cannot access the printer utility in order to view ink cartridge levels & perform printer maintenance. When I open the printer utility, there is no printer listed. According to Epson support, this problem occurs since I am contacted to the printer wirelessly. If indeed true, is there a workaround to access the printer utility.

Thank you.
