Hi there, Thanks for dropping by. I really hope I can help you out with your IT issues, quickly and efficiently.
As a first action and in order to attempt to remove the printers, do you have an option to right click on the printer and select "Deploy with Group Policy" if so, you should be able to remove the printers - this will be a start for you hopefully, so please try to carry this out and get back to me as to how you get on please.
Another consideration is the drivers. You will need to consider the 64bit print server and if it requires 32bit drivers. I look forward to hearing from you.
