For a RIP the printer profile usually contains almost all data for ink limitation, black generation, mixing, dot weaving, (possibly media transport adjustments, head height, auto cut enabled or not) and the integrated ICC profile describes the gamut details of the CMYK(or N-color) device; the printer.
If an OEM driver is used for an inkjet the parts are usually separated, the media preset (made active with the media choice in the driver) has the description for ink limitation etc but includes an RGB>CMYK translation for that paper and then a simple separate ICC printer profile describes the gamut from the RGB perspective. The printer is in that color management approach seen as an RGB-device, like a monitor is. In the HP Z3200 drivers the RGB-device profile can be linked permanently to the media preset and be packed in one .OMS file. Third party media suppliers can get the tools from HP to create the total .OMS data file. This gets close to the RIP approach but the profiling remains an RGB-device type one.
