Problem in printing from LPD - Solved

[Suresh]

I found the solution for LPD printing issue. The solution is that the CUPS requires tmp folder in /var/ directory. i.e /var/tmp/ folder should be needed by CUPS to handle LPD print requests. In my embedded product,the /var/tmp/ folder was not present. LPRng does not require the presence of this folder.  I don't know the exact description of the solution. I am undergoing study on this solution. Once i found the logical result i will mail to this forum.
