Problem connecting to printer

We have a wireless network which all computers on our shop floor are connected to.  One of these computers has a printer attached to it which is shared.  We can connect to this shared printer from any of the other computers on the wireless network.  However, we can not connect to this printer from any  computer that is hard wired into the network even though we can see it listed in the directory when we try to add the printer.
Any ideas?

First question is the Wireless Lan on the same Lan as the Computers that are Hard wired?

Most put the wireless on another network for security of the LAN.

Second is this printer connected to the network with a cable or just wirelessly

Some wireless printer have both.

First question:  Yes, all computers are all on the same network.  It is all one domain.
Second question:  The printer is connecting to the computer via cable.

Are the wired computers Windows 7 or XP or a mix?

On the wired computers bring up the network do you see that printer share listed?
Do you see that computer listed?

Check network and sharing  is on all computers.

Do you have windows firewall on?

What antivirus program is running?

The wired computers are a mixture of XP and 7.
On the wired computers when we go to Add Printer and specify "Find the printer in the directory, we see the printer.   When we try to connect to it we get the message "windows cannot connect to the printer.Either the printer name was type incorrectly, or the specified printer has lost it's connection to the server."
I can see the computer listed in Active Directory.
We have tried turning the firewall on or off but it has no affect.
We are running Trend Micro antivirus.

Try using the UNC path to the printer in the Add Printer Wizard.
Add Printer > Network Printer > Connect to this printer (Second Bullet)
Click Next to browse (leaving the Name field blank) or type the UNC path to the printer (i.e. \\Computername\Printername)

When I typed the UNC path name it connected me to the printer.
Then I deleted the printer from my list of printers and then went through the normal Add Printer process, finding and selecting it from the directory,  and that connected me to the printer also.
don't know why.  It didn't work until now.
anyway, thank you very much for the help.
