## 7. Fine Tuning CUPS-Related Ports

If CUPS is going to serve as the primary printing system, then one may choose to optionally add certain knobs to `/etc/make.conf` that will emphasize CUPS over other printing options. Some of these “knobs” that one may want to add are:

WITH_CUPS=YES CUPS_OVERWRITE_BASE=YES WITHOUT_LPR=YES

The first knob, `WITH_CUPS`, adds CUPS support to ports where applicable. The second knob, `CUPS_OVERWRITE_BASE`, will fix certain symlinks and paths that would otherwise apply to the default FreeBSD printing system, LPR, and will prevent these fixes from being reverted upon the next `buildworld` system upgrade. The third knob, `WITHOUT_LPR`, will prevent LPR support from being added to ports where applicable.
