ABSTRACT:
A computer communicates with a printer. The computer has a printer communication controller for controlling one-way and two-way modes for printing. The printer has a printing controller for controlling the one-way and two-way modes. The computer sends a switching signal to the printer through a switching signal line, to switch the printer from the one-way mode to the two-way mode. The switching signal is a signal in response to which the printer can return a response to the computer through a reception channel even if the printer is offline. Upon receiving the switching signal, the printer returns a response to the computer and switches to a pseudo two-way mode that is a temporary online state. If the computer sends a printing start command thereafter to the printer, the printer switches from the pseudo two-way mode to the two-way mode. This arrangement easily switches the one-way and two-way modes from one to another. Also provided are a printer system involving the computer and printer, a printing control method for operating the computer in the manner mentioned above, and a medium for recording a program that achieves the printing control method.
