My problem is still there. Everything I have tried hasn't worked. The machine from which I am trying to print (Mandrake 9.0) says that the remote host refused to accept the control file but the remote host (Debian Testing) doesn't show any signs of access or attempted access in the logs. Stopping the firewall on the remote host makes no difference. Is there any way that I can find out on which machine the problem lies? All other network functions perform properly. I think that the Mandrake machine is lying to me but I can't prove it. Barry Samuels
