Abstract

The IBM 3287 printer, which operates in a data processing environment, has several combinations of special hardware options, some of which are mutually exclusive. A word processor has a different printer which emulates the functions of a 3287 printer. The conventional 3287 printer requires actual, physical wiring changes to provide the special options. These changes cannot be made physically to the word processing printer. It is nevertheless desirable to provide the operator with some means of obtaining these options of the 3287 printer, so that host applications will print properly, without change, on the word processing printer performing the 3287 emulation. This is accomplished by presenting the operator with menu options which provide all combinations of the 3287 hardware options.

Emulation of IBM 3287 Printer Hardware Options

The IBM 3287 printer, which operates in a data processing environment, has several combinations of special hardware options, some of which are mutually exclusive. A word processor has a different printer which emulates the functions of a 3287 printer. The conventional 3287 printer requires actual, physical wiring changes to provide the special options. These changes cannot be made physically to the word processing printer. It is nevertheless desirable to provide the operator with some means of obtaining these options of the 3287 printer, so that host applications will print properly, without change, on the word processing printer performing the 3287 emulation. This is accomplished by presenting the operator with menu options which provide all combinations of the 3287 hardware options. The combining of duplicate hardware items with yes/no choices and the use of multiple-choice selection for mutually exclusive items provide the operator with a simple but effective means to specify the print characteristics desired. This solution allows installations currently using the selected hardware options on a 3287 printer to migrate to the IBM 3270 emulation without changing operating procedures. The options provided allow reformatting of host-initiated data at the word processor without host intervention. The three specific options provided by the 3270 emulation feature are as follows: 1.
