Aha, got it. But I assume this is the kind of thing a lab does--there isn't any affordable machine for the home user?
There was never an "affordable machine for the home user" during the era of silver gelatin printing. That is, one used an enlarger and processed by hand via trays & tongs; or contact printed and again used trays and tongs. The "affordable machine" was a home-based darkroom.
Todd had the correct answer, for the home user:
"
Scan you image, print with your ink jet to Pictorio OHP White Film, Print in darkroom as usual. I've done this many times and a quick google search for Dan Burkholder will yield the answers.

Just to elaborate, the method Todd is recommending is contact printing in a darkroom, using a digitally-produced negative via inkjet printer. Keep in mind that there are a number of good silver papers out there, and one new contact printing paper recent arrived on the market, Michael Smith's Lodima silver chloride paper, which it is claimed is every bit as good as the venerable Azo paper, which Kodak killed off in 2005 after ~100 years of continuous production.
Contact printing onto silver gelatin paper is as simple as a low wattage light bulb suspended above your darkroom table, a timer, a thick sheet of glass a bit larger than your print size, and processing trays and chemistry. This is how Edward Weston did it, contact printing from 8"X10" negatives.
Contact printing also lends itself to alternative processes, which usually require (along with Lodima silver chloride papers) more UV in the light source. All of these are possible with the production of a digital negative via a medium like Pictorio.
See the APUG forums for more detailed discussions around contact printing.
