Unless you need to go that way and can utilize the printer to help offset the cost, I feel the way to go is Staples or another printer company. I always have them print on a overhead projector sheet so I can do a final view of the colors and see how close the match. The only time I have problems is when I need to be translucent, which is a lot of times. You want to let light travel thru but not able to see the bulbs under the glass. I sometimes use a glass paint found in Dick Blick. You dont want to heat it in the oven. Bujt I use the frosted to use over the decal once applied to help with it. Sometime I use to applications of decals, one for the color and another one to make it translucent, like a light white. It all depends on the color and quality of the printer. By looking at your glass, if you can get the replacement for 200$, you will save time and get a better quality glass. This process works great with background and basic colors but when it comes to mirrored arrows and trim, it doesnt work well, and I see that the area your looking to work on has a good deal of that type of trim. There is a company in Europe that does replacement glasses and if you would like, I can get you their info. A little pricey but the work I have seen, you cant get any better. He does a lot of Bingo glasses.
