    Its very easy, Noritsu, has many machines that take a digital file and expose through and LED exposure system on RA-4 paper, we had one at the shop that I worked at, very simple process, you just tell the machine what media your getting the image from, either negative or digital, as well as scanner image, it loads the image onto the computer monitor and makes the exposure, then processes in Chemistry as normal..

    The process has actually been around for a number of years now.

    The man is right. The Fuji Frontier processors that are popular in many photofinishing shops take a digital image (or scan a film image at high resolution) and then use lasers to expose color photographic paper and chemical wet processes to develop it. The results are very good, and the same machine can be used to make anything from 4X6 to 20X30 prints by just switching magazines and pushing a couple of buttons. As noted above, several other manufacturers of photofinishing make comparable equipment.

    My concern is that no one has mentioned the best recipe for crow, basted in Rodinal. Anything is better with Rodinal, even digital RA-4 prints!

    I have 12x16 color prints made on a Noritsu machine from 35mm and 645.The owner told me they are output at 300 dpi,which is the industry standard, and the negatives are scanned at whatever resolution is required to give this.

    Of course , I think my hand prints from 645 Delta 100 look slightly sharper but few people notice.

    It's really hard to escape--it's almost always how machine prints are made these days--the machine scans, prints, and throws the file away. Optical machine prints are getting seriously hard to find.

    slightly off topic,but...

    ...there is a machine which will output a digital file via coloured lasers onto film-a snip at a mere £7000 per machine!
    A common mistake people made when designing something completely foolproof was to underestimate the ingenuity of complete fools.

    Computers are incredibly stupid,but they are capable of being incredibly stupid many millions of times a second.

    Another way to do this is to use a DeVere 504DS enlarger which is specifically made to project digital files onto standard B&W photographic paper.

    The image taken with a digital camera would be converted to B&W in Photoshop. It would then be inverted in Photoshop (changed from a positive to negative image); and adjusted (curves applied, histogram adjusted, etc.) as required for best printing through the 504DS.

    The enlarger uses an LCD with a light source behind it (just like an LCD computer display, LCD video display, or LCD video projector). Using the digital enlarger, you project the B&W file image onto any standard B&W photo paper and process using the B&W paper developer of your choice then fix, wash, and tone....whatever you want to do as part of your B&W photo processing workflow.

    Here are web links you can look at the equipment

    So, yes it is totally possible to print a digital camera image onto standard B&W photo paper using a digital enlarger.

    If the existance of digital enlargers is what is needed to keep traditional papers going then so be it, doesn't mean you have to do it digitaly it means that its keeping the paper in production.
