SAP uses its own spooling and print system within R/3. This means that it provides a uniform interface with the printer, independent of the computer platform being used. For this reason, SAP requires its own printer drivers, which are referred to as Device Types (DTS = Device Type Support). Their task is to convert all formatting commands (for example bold, italics etc., or special printer functions, such as which tray the paper should be pulled in from) into the form of command required by the printer. Using these drivers, our printers print at the full nominal speed from SAP R3 and our features can be utilized.
