Thus:

Printer == 10.0.0.3
PC1 == 10.0.0.3
PC2 == 10.0.0.4

I will ignore the Vbox machine since that one is usually something that is
natted to the host IP, and as long as your host has intarwebz your virtual
machine will also have internet.

Try this:

1 - Switch of the printer, or plug out it's network cable.
2 - Reboot PC no 1, or if you know how, restart network manager and see if
it gets an internet connection.

IF THAT WORKS;

3 - CHANGE THE PRINTER IP! It has not been assigned by DHCP like you
thought, or it has a glitch and the IP persisted after the DHCP lease
expired.,
4 - Change the destination IP for the printer on all the machines that they
can see the printer.
5 - print and surf.

IF THAT DOES NOT WORK.

3 - Check if PC1 has an IP assigned via DHCP after all, it might be that it
has been assigned manually, and that the gateway address is incorrect.
4 - IF the printer gets it's IP via DHCP from the router, it might be a
good idea to assign a manual IP address in any case - it will cause
problems if the IP ever changes when a lease expires/gets renewed/reboot
ensues/etc.

The fact that two devices has the same IP in the same subnet tells me that
one of them has the IP set manually. Smart money is that it may be the case
that BOTH have manually set IP's, since one of them would have gotten a new
IP from the DHCP server when the conflict happened.

Let us know ;)
