SysV printing requests & temp directories too large

I'm running SCO 505 and have 62 print queues. I am used to BSD style printing where each print queue has it's own work directory (/usr/spool/lpd/<prt>). I was forced off of BSD style printing due to /etc/printcap not supporting filters (does not work). I now use netcat inside of a print filter via SYS5 printing. I would like to configure each print queue (SYSV) with it's own requests and temp directories, as these directories are too large. I can't do an ls in either directory during production hours, there too many print jobs queued up. Gary Quiring
