Working with ten different media on ten different sizes, rolls, sheets, true b&w, another(better) screening, controlled ink lay-down, step-and-repeat, tiling a.s.o.; purchase ImagePrint

Half of that is also covered by Qimage + its job, session, setting, etc recall feature + the OEM driver. Qimage's extrapolation, up and down, adding to the usually excellent screening of today's drivers.
True B&W is available at least in the HP Z model drivers.
Postscript interpretation by Adobe applications or Ghostscript, Jaws, etc if that kind of format printing isn't your usual job.
RIPs can have additional features like printing registration marks for cutting plotters or Fotoba trimmers.
There is not that much left for RIPs that is unique but the certified proofing, film separations and driving special printers that have no normal drivers. The last are usually printing on substrates that need that controlled ink lay down. Most substrates usable on water based inkjet printers can rely on one of the media presets already available in the drivers or on slightly adapted media presets as possible with the HP Z models.
