For most printers you have two choices:
Option 1 is inexpensive, you only have to add a card reader with the networking option, but you lose the advantage of not printing unwanted print jobs.
Option 2 costs quite a bit more. Since most printers can't interface with Papercut or other print management solutions directly, you would have to add a tablet-like device to see and choose your print jobs. These tablets can cost around $1,500...this adds quite a bit of cost and reduces the ROI.
