Perhaps I should say "the platform vendor should create as many
drivers as possible", rather than "the platform vendor should
create the driver".

Specifically, I was thinking in terms of the "port monitor"
side of the driver, using Windows terminology. (That is,
the part of the driver responsible for transmitting the
print job to the printer, and handling all details of that

You're correct in pointing out the need for certain printer
vendors (or their subcontractors) to develop special imaging
components of the "driver". This part of the "driver" is not
what I was referring to.

> Some drivers need to incorporate RGB to CMYK color conversion, perhaps with multiple gamut intents, all dependent upon device-unique screening, ink colors, etc. etc. Unique features, such as PostScript allows in PPDs, must be included. These are product differentiators and potential competitive advantages. It therefore seems that the printer vendor should be responsible for driver development -- even if it is subcontracted -- not the platform vendor.
> Are you saying that the "driver" is only a shell and that the vendors can deal with everything through PPDs or their non-PostScript PDL equivalents? Even in that case, I recall one major vendor shipping an "obsolete" driver with his new machine because the "current" platform driver shell could not support his features/needs.
