If i removed /var/tmp/ folder in Linux PC 1, giving test print from 
Linux PC 2 via LPD. I read the error_log file in Linux PC 2, it was 
found that the error message "R*emote Host does not accept the control 
file*". The print service in Linux PC 2 keep on spooling the job to the 
destination. As soon as i create a /var/tmp/ directory in Linux PC 1 , 
the job from Linux PC 2 via LPD successfully reached the Linux PC 1.

Note that the printing locally in Linux PC 1 with or without /var/tmp/ 
directory does not provide this problem.

My query is that why printing via LPD alone require this /var/tmp/ 
folder.  I searched CUPS source code, but i didn't get any idea.
