Collate PostScript options available from the ps2afp transform
When a PostScript file contains the collate key, the ps2afp transform recognizes that key, and the resulting AFP output has the copies collated. Not all PostScript printers natively support the PostScript collate key, but if you used a PSF other-driver DSS, InfoPrint Manager exploits this new transform feature and creates PCL that you can print on that same printer and get collated copies.
Note: The collation function requires more disk space, so increase the space in
/var/psfto store the temporary file for collation.
