To me, this looks like state pressure rather than a normal business decision. I cannot see a convincing reason for it otherwise. If these printers are used in professional settings, users may be unknowingly sending prototypes, designs, and internal project data to China. That kind of access would be extremely valuable, especially if the company can identify the buyer, their location, and their field of work. Given the relationship between Chinese companies and the Chinese state, corporate espionage seems like the most plausible explanation.

Don't forget that you are having the cloud hosted services generate and send executable code to a device inside your corporate firewall. I can see all kinds of potential issues corporate security would have just based on that fact alone.
