Sorry mate, wish I could help. You're basically using one Mac as a printer "hub" for wireless network printing, but only three Macs are able to access the printer settings when printing? For example, what exactly happens when printing in Photoshop? Normally there would be an expanded window option to chose print quality, paper handling, color correction, etc. This is not happening with all but three of the Macs?
Have you tried uninstalling the printers from the Macs that are giving you trouble, then control-clicking in the list of printers box in System Preferencs and selecting "Reset Printing System" (or such, I forget the exact words)? When I've come across printing inconsistencies I simply start from scratch, but not by uninstalling and reinstalling software/drivers, but by resetting the entire system then simply adding the needed printer.
If you can print with every Mac there should not be a sharing issue. It's odd that there are no printing options when you print. How do you print then? Does any dialog box display or does it just print without giving you a dialog box for printing options? Very odd.
Also, what kind of wireless system is running? Are you simply using a DHCP for each system on a wireless network through a router such as Linksys or Apple Airports? Perhaps getting a router with a USB connection for wireless printing might solve the issue. Printer sharing over many systems through one system DHCP might be taxing (?). No idea.
.... and upgrade to "Snow Leopard"!
