Data sent from a personal computer (PC) to a printer by a printer interface is momentarily stopped through a Print Spooler program, which is resident in the PC memory, so that the printer interface can be used to cause the printer to go offline and perform functions, such as moving the paper up or down. A Printer Communication Routine program, which is resident in the PC memory, controls the printer through a printer interface. The Printer Communication Routine program causes the printer to go offline and perform functions, such as moving the paper up and down. During this offline command processing, it is imperative that no other resident application program in the PC memory attempt to use the printer interface or the data will end up interspersed with the offline commands to the printer.
