When you have done a very good job with what you have graphically designed, it's very important to use an equally a very good printer to give you exactly what you have put in work.
Which printer have you been using that have always given you the best output of the job you worked on?
Where I used to work at a marketing company in Chicago, we had an awesome color printer, that for that time in the 90s was perfect! It was also very expensive...maybe a Canon? I can't remember the brand, but I was using it before they put a password lock on it.
