welcome to the forum!
I think that your question is not specific to IPCop, it is a situation relevant for whatever firewall you use. But first some other points.
The box between IPCop and your PC1, PC2, ... : is that really a router!? Probably it is a switch! (If your PCs obtain an IP address of the GREEN IPCop network i.e. 192.168.2.x/255.255.255.0), then it is a switch, not a router.
Actually your IPCop is a router which is setup with some predefined rules. For the GREEN network all traffic to the RED network is allowed by default, but not vice versam (default as well). This default rule set can be tweaked by custom rules.
This means that access to your printer 192.168.1.xx should be possible from the GREEN network by default.
Thanks for your reply... Sorry for my mistake, i meant switch and not router...
But from red interface, i have only internet, cant 'see' any pc connected to modem-router with ip 192.168.1.xx
