did he create one universal profile that all the machines could hit?
Be sure to understand the term "profile" in context. With regards to color management proper, a profile is most often considered to be an ICC color profile specifically. Unfortunately creating confusion, about the same era (1990s) as the term was propagated, "profile" was also used to mean both general and other specific settings for printing machines, especially inkjet printers, and may not have included any ICC profile because they were not necessarily in common use at the time.
A "media profile" say, is something rather different and more broad (settings for ink load, calibration, resolution, etc.) than an ICC color profile specifically. The ICC is only a component of a more general printing setup and is specific to a particular printer / ink / media setup.
So, a "universal profile that machines could hit" is not really a thing. Although ICC color profiles may be transferred and used among different printers, the smaller color gamut printers would be a significant limiting factor but is common, none the less. An example is aqueous inkjet printers capable of very wide color gamut used as proofing devices for rather limited color gamut of CMYK-only offset printing presses.
It's sometimes a conundrum, a shop doesn't normally want to limit wide color gamut machines to their lowest color gamut machines just so they all truly match.
