Think of it like television, you turn a dial and pictures and sound come out, sometimes with some coherence. But, the RIP converts the digital image into a form that the printer can convert into an image. A digital image is made up of picture elements(pixels) that are typically a group of three "words" either eight or sixteen places long. White would be the word 11111111, 11111111, 11111111 and black would be 00000000, 00000000, 00000000 in the eight place version. All other colors would be some variation of 0's and 1's. A printer can not directly use this information as the inks are not pure red, green, and blue, the quantity of ink and the spacing of the ink is not in the same proportion as the file full of numbers that your digital file is. R is for Raster. A fax is almost a pure raster image, it is a grid of white and black that only seems to form something we can recognise. In reality it is a two dimensional array with x,y coordinates assigned either white or black. For a digital file it is a two dimensional grid with the aforementioned group of numbers indicating a specific color. The I is for image and the word means the standard dictionary definition. The P stands for processor and all that means is that there is an equation that tells the printer that at coordinate x,y the printer should drop so many picolitres of cyan, magenta, and yellow ink. The reason you need a specific program for each paper and ink combination is that the inks are not linear in the human eyes perception of color. In plain English that means that a specific color of red will take different quantities of of the different inks depending on the paper that is used. This is the same in the chemical process you know; different papers respond differently to developers and their dilutions in varied ways. What you can respond to under a safelight, the printer needs a program to do. You don't really need to know any of this to print digitally. You don't really need to know any of this if you want someone else to print your images while you are waiting to set up your new darkroom. Stay on the list Marc, we will get back to Leica's fairly soon. Just as in the late sixties people forgot about rangefinders but came back, digital is new and a shiny new toy that we all need to talk about because it is new. Besides, I am having a blast with my Contax III and a Contax II clone in the form of a 1950 Kiev. I need you around to help me out with the intricacies of Zeiss.
