if its not wireless then you wont find the ip btw update the drivers for the printers. that will definitely solve the problem
and also do this
There must be incompatible printer drivers exist on Desktop2. As the printer drivers are loaded by one process when a printing job starts, the incompatible driver will affect the printing job even when you print with another printer driver. I suggest you follow the steps below to clear the printing sub system, and then reinstall the printer on Desktop 2.
Step 1
======
Start Windows Explorer, and then rename all files and folders in the following two folders:
c:\windows\system32\spool\drivers\w32x86
To rename a file, we can right click the file and select Rename.
Step 2
======
1. Click Start, type REGEDIT in the Start Search Bar, and then press ENTER.
2. Navigate to and then click the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Environment\Windows NT x86
View the list of subkeys. There should be only the following subkeys:
Drivers
Print Processors
If there are any keys other than those listed above, follow these steps:
a. On the File menu, click Export.
b. In the File Name box, type a descriptive name for this key -- for example, type WindowsNTx86regkey -- and then click Save to save it to your local Desktop.
We can use this backup of the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Environment\Windows NT x86 registry key to restore the key if you experience any problems after you complete this procedure.
c. Delete all keys other than Drivers and Print Processors.
Step 3
======
Navigate to and click the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Monitors registry key. View the list of subkeys. There should be only the following subkeys:
BJ Language Monitor
Local Port
Microsoft Document Imaging Writer Monitor
Microsoft Shared Fax Monitor
Standard TCP/IP Port
USB Monitor
WSD Port
If there are any keys other than those listed in above, follow these steps to delete them:
a. On the File menu, click Export.
b. In the File Name box, type a descriptive name for this key -- for example, type Monitorsregkey -- and then click Save to save it to your local Desktop.
We can use this backup of the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Monitors registry key to restore the key if you experience any problems after you complete this procedure.
c. Delete all keys other than the 5 listed above.
Step 4. Disconnect the printer cable from the computer, and then restart the computer.
Step 5. Reconnect the printer cable to the computer, install the Windows 7 compatible printer and add the printer as a shared printer with the method in my previous email.
