Ok bare with me because I am a little new at some of this. I have had some college classes with digital photography so I am familiar with some things. Let's say I want to buy a printer to print digital pictures. I want something that will be able to print a poster size picture if needed. What is a good printer to get that is affordable and will give me quality results? Also I am unfamiliar with how you go with setting up the printer to make it how it looks on your computer screen. I know you have put something on your monitor and it calibrates it or something like that. I am wanting to start a side business taking pictures is why I am asking these questions. I also have a Nikon D40. Do you think I need to upgrade to a better camera? I know I will have more questions but for now that should do. Also would like some critique on this picture I took of my car. I havn't touched it in any programs yet.
