Conflicts with printer connection: ethernet, wireless

Thanks for your responses!
Unfortunately I can't give out our IP addresses or other information of that type online. I'm sorry if that makes my questions harder to answer!

I should specify again--I need the desktop (connected by ethernet) and using a network I'll call C3) to be a part of the subnet that the printer (which is using wireless network B2) is already on.

We use a large router with about 50 ports. It seems that all these networks are all funneling through this one large router that I can see, but cannot tamper with. It belongs to a large hospital that is having construction done. The hospital lets the construction companies work in an office building next to it and gives us (the various construction companies) internet access. They have multiple networks, and the one my company was previously using (A1) was too slow for our location, so we switched to a faster one (B2).
I apologize if I'm not using correct terminology. I am not a tech expert but I do a lot of minor tech support for my office. This however is beyond my ability.

I was able to find all of the information that msmart discussed.
If I want to get the desktop and printer to be part of the same subnet, how would I do this?

Thank you!

In the old days (when I was young) I routed networks through a Windows NT machine.
IMO opinion this is possible in all versions of Windows.
As I understand you want all users having internet access through the hospital server, but handle your own file and printer sharing on your own network.
At the time you could type routing commands, but maybe now you need to go through the network centre.
Have a PC with 2 network cards and share the internet connection to your network.

@DCSBS, If you wish to discuss sensitive or personal information, then why not PM @msmart and use that facility to openly show your IP address privately with it him directly, if he is willing of course..

Yes, I'm willing to communicate via PM.

Doesn't the hospital have IT people that can help?

Have you compared the IP settings with PCs that CAN print with the one that can't?

With Windows it's relatively easy to set up the computer to look for the printer by IP address. Then, if you later change the IP address, that will prevent printing. That tends to happen a lot, and it's one possible source of your problem.

It's better to set it up to look for the printer by name, but Windows makes a real hash of the setup procedure. I don't recall the details without looking, and in any case I don't want to get into Windows 8.

Let us know what the cause turns out to be.

You mean you have two router ?? You try using WPS push button ? to add devices to router ?

Manually why you not add MAC (of your desktop) address to router and give the desktop new IP address.
If your router has usb port it must use default gateway 192.168.0.1 mask 255.255.255.0.

Without seeing a network diagram I'm not sure I can reliably interpret the way things are hooked up here but a couple of critical questions that may help nail things down better.

1. How are the other workstations/computers connecting to the printer/network? Is it via the Wireless B2 network or are they using the C3 hardwired LAN?

2. If it's C3, can the other computers see the one that's having problems within the same workgroup/domain?

My guess is that the other machines are all using wireless and thus don't touch C3, or the problem workstation is not properly hooked into the domain and circumspectly is not receiving the correct DHCP or static IP/Gateway/DNS settings to allow it access to the printers network.

As a workaround it may be possible to hook the printer into the C3 via a wired cable. The Wireless and Ethernet connections do not need to be on the same subnet to be able to communicate with the different clients, so it's just a practical issue of network socket and appropriate patch panel cabling to C3.

Oh, yes, you can't forget about the socket.

Brilliant @msmart, Now why didn’t I think of that…?
