Okay, here are some more detailed timings.

Power off --> Ready: 25 seconds
Power Save --> Ready: 0 seconds
Ready --> blinking data received light: 9.6 seconds
Blinking light --> Startup (motors whirring, etc.): 1 second
Startup --> Page Out: 14 seconds.

It is the third stage (the 9.6 seconds from the time I tell the computer to Print until the green data acquisition light starts to blink) that I was curious about. However, since there is only a 1 second delay before the printer goes into action (motors spin up, paper is grabbed and sent on its path, etc.) I suspect that the start of the blinking is not signaling the beginning of data acquisition,but perhaps the conclusion of data for the first page.

But that doesn't seem right either. If it takes that long for the first page, how does it do the remaining pages (in a multi-page print job) at the rate of one page every three seconds?

Other printers I have used always started the blinking data light within two or three seconds of sending the print command.
