Hi i tried printing a 4 page ps document from the pstops filter. The output file from the file becomes blank on the combinations like 2,3; 2,3,4; 2,4; i.e., it prints only the combinations that accompany the first page like 1,2; 1,4; 1,3. Im using cups-1.3.6 on Fc6 Will attach the ps file for more info. Regards Ashok
