unable to share printer via wireless

[Guest Robert J. Lafayette]

both computers have XP Home, SP2,

 

mine is computer A

hers is computer B

printer is X, USB connected to A

computer c- wireless router.

 

A and B share a wireless Internet connection where Internet comes from a

main wireless router connected to computer C.

 

I wish to share printer that is hard connected to computer A with computer B

using wireless or Internet system if possible. Computer c may or may not

wish to use printer X, ever.

 

Made printer X, which is connected to computer A available for sharing. Via

printer/ fax in control panel.

 

Can't seem to get computer B connected to printer x in computer A and

something may be missing.

 

do I first need to do something with computer C to set up printer X so A and

B can share it?

 

if this is at all possible, the more detail in instruction, the better.

 

Please.

 

Cordially,

Robert
