Thanks for your suggestion. It looks mysterious. after I set up the IP of print server as localhost, it worked well. I asked my supervisor. he said localhost means the server. So it looks the APEX is using OC4J on the server, not OC4J on 10.22.8.254.
another question is the printing port is 8888, which is exactly same as Oracle APEX is using on the server. Which makes me more confused. would n not there be a conflict on prot of APEx listener and printing?The APEX EPG uses port 8080 by default.
