I was referred to Bill to help set up a rather complicated service on our printer. I emailed Bill to ask my question and he got back to me within minutes asking me to call him when I had a few moments to go over the process. I thought there would be no way someone can explain what I wanted over the phone but he managed to do it in such a simple efficient manner! He knew exactly what screen I was on and walked me through the entire process with ease! Thank you Caltronics for having such knowledgeable employees on staff! Thank you Bill!
