When you define a printer on machine A as shared, s-c-p on machine B can't "see" it. On machine B if you tell s-c-p to search for network printers using the machine A hostname, it comes up with nothing but ipp://hostname/ipp. s-c-p periodically breaks like this, and then magically gets fixed. What is out of sync here between s-c-p and (I assume) cups ?
