I know lots of different games, some of which even have technomagic elements, but with all those qualifiers put together? I don't know of anything off the top of my head.
1. Technomagic doesn't tend to be popular in general.
2. Future stuff tends to be "Sci-Fi" and therefore heads off into space.
3. Non-d20... you're into the niche area of a niche hobby.
4. "In print" I'm guessing means "company still exists" or "company still supports the product".
The technomagic settings that I know of:
Red Star (d20 Modern) - Retro-history. WW2 sort of blended with semi-futuristic look. Carries the d20 logo so Green Ronin is probably going to have to dump them, or sticker over them or something.
Everstone (BESMd20) - Fantasy world, blended with future looking runetech. Carries the d20 logo, distributed by Guardians of Order (who are out of business). Not hard to find, but an awful lot of strikes against it for you.
Secret of Zir'An (Finesse system) - technomagic in a 1920's sort of world. Distributed by White Wolf until they basically dropped the game. Paragon Games still sort of technically exists, but what's out there is all there is.
Dragonstar (D&D 3.0) - D&D in space. Old game line of FFG, which they dropped. Doubt they'll re-tool it either, but anything is possible.
Arsenal / Factory (d20) - technomagic source books. Put out by Perpetrated Press. Company ceased to exist a long time ago. Still pretty easy to pick these up though, and very cheaply. Arsenal covers various magic bits and weapons, Factory is all about robots.
Rifts (Palladium) - some technomagic stuff. Post apocalyptic future where magic came back. Technomages exist within the setting, but they're just one small part of a whole big world of crazyness.
Eberron (d20) - technomagic, I guess. I personally hesitate to really list it, as it doesn't really strike me as a "technomagic" setting, despite some people's complaints about warforge being another name for "robot". On the whole, Eberron really felt more like "D&D" with a new coat of makeup. A few throw-away bits that are sorta technomagicy, but it's really still just D&D.
