it works for me now.
if i connect to the network printer using IP address instead of computer name, it prints immediately. i guess it is the server name resolving that hit me 15-20 seconds.
eg:
smb://192.168.0.111/EpsonLX
instead of:
smb://MYSERVER/EpsonLX
i know it may not be the best way to do it, but it solved my problem for now. thanks for all the helps and responses.
