Problem of generating file from samba print share

[timmy tang]

Hi all,
I am using samba 2.2.1a-4 on RH linux 7.2. I created a print share to convert incoming print file to pdf file through a program called ps2pdf. I would like to generate the pdf file with filename same as the original print file name. I use the %s variable to get the name. Is that correct? 
I used to use this method with older RH package and it ran correctly. However when I upgrade it to use samba 2.2.1a-4 now, I can generate the pdf file with different file name start with "smbprn.<xxx>". I can't get the original print file name any longer. Why?

Timmy
