Abstract

In the present day text or word processing environment, the word processor often requires access to a host data processor through a low cost data link or data processing and records capability. When such a link has been established, it is efficient practice to utilize the printer associated with the word processing system for data processing printing operations. In such a case, the data processor is connected to the printer through the word processing system. Operator interactive capability is provided for switching from word processing sessions to data processing sessions wherein the word processor emulates a data processing terminal and the printer associated with the word processor emulates a DP printer.

Word Processor Emulation of a Data Processing - Host Controlled Multiple Device Printing

In the present day text or word processing environment, the word processor often requires access to a host data processor through a low cost data link or data processing and records capability. When such a link has been established, it is efficient practice to utilize the printer associated with the word processing system for data processing printing operations. In such a case, the data processor is connected to the printer through the word processing system. Operator interactive capability is provided for switching from word processing sessions to data processing sessions wherein the word processor emulates a data processing terminal and the printer associated with the word processor emulates a DP printer.

The present approach is directed to a system wherein the word processing printer emulates such a data processing printer. The algorithm involved specifically addresses a situation where there has been an error in one of multiple devices being emulated on the word processing system and the device in which the error occurs is an emulation of a printer. The present algorithm determines whether the error is on all of the devices or less than all. If the error is on less than all of the devices, the algorithm provides for a continuation of the output operation with respect to the devices such as the printer where there is no error condition present.

In accordance with the present algorithm, the output from the host processor may be directed to two devices, i.e., a printer and/or diskette. When the print destination is being directed to both of the devices, an error on one device should not halt the printing on the other device. Alternatively, the two devices may be printers. In accordance with the present approach, if there is an error in one of the devices, printing is stopped on that device while printing is continued on the other device.

When an error occurs on a device, the algorithm either cancels the printer destination to that device (and informs the operator) or reports to the control unit (this depends on the number of devices to which the operator has directed the output). If the output is directed to both devices, the destination is cancelled. If it is directed to only one device, the error is reported. When the destination is cancelled, the operator is prompted to and has a responsibility of respecifying the print destination if he...
