invalid handle (printer) NT TSC

Two pc’s (Win95, Win98SE) running NT terminal server client had shared printers that were upgraded. The old printers were deleted, the new ones were added and shared. Both printers work properly across the network, including the NT servers, however neither workstation can print through the Terminal Server Client session, receiving an error ‘page failed to print. The handle is invalid’. I have removed the printers, all sharings & mapped ports, and reinstalled, only to receive the same error. Anysuggestions please?
