My CUPS runneth over....

I was asked recently by one of my clients about Linux printing.  You see, they were about to embark on a conversion in their environment going from a proprietary printing solution running on Legacy UNIX and they wanted to host it all on their much more agile, much less expensive linux servers.

I was excited to share my experiences.  Our old group had configured a home-grown LAMP solution around CUPS that worked out fairly well for us.  For those of you out there thinking about hosting printing on Linux, this article might help steer you the right direction:

CUPS certainly isn't the only way to go, but a lot of times a FOSS solution  works really, really well.  So what do you all think?  Have any great cost-savings projects where you implemented CUPS or some other tool for printing?  Have any good 3rd-party products you'd raise your hand to endorse to streamline operations?  We'd LOVE to hear from you!
