IP Address Conflict With Printer?

Specs: OSX Lion, Pentium Dual T3200 2
Hi guys, I have a strange IP address problem that I hope you may be able to help me with.

I have a my MacBook hooked up to the same network as my printer and I have set the printer as a static IP (in this case so that I don't have to keep configuring it every time I restart my router.

The problem is, my wife's laptop (Windows 7) which is also on the same network is getting an IP address conflict and I am unable to print from my MacBook until she switches her machine on.

Any ideas how to resolve this?

Thank you all in advance

Do you mean until your wife turns her machine off!

Change the printer IP to one outside of the scope of the DHCP server in the router and no computers will get the same address as the printer.

Your router manual will tell you hoe to set the DHCP scope.

No I mean until she turns her machine ON. Which is why it's a strange one.

I should have said that her laptop is also connected to the printer (via the router) so she'll also be connecting to it via the same IP address

Sounds like a setup error to me, not an IP conflict.

It appears that your Macbook is currently routed through your wife's machine to access the printer, hence when your wife's machine is turned off, there is no path to the printer.

You need to check your network setup.

Hi thanks for your reply. But unfortunately it's just not the case. The MacBook is connected directly to the printer IP address.

I have told my router to reserve the address in DHCP to see if it makes any difference. Not sure yet though
