Abstract

When using the printer profile utility, the user is required to make certain choices with respect to the printer parameters. In a typical example, the screen below might be displayed to allow the user to change the printing pitch. If the user makes an invalid choice, as, for example, specifying the pitch 12 rather than the valid choice b, an error message is displayed followed by the input prompt. In this example, the appearance of the screen would be as shown below. If the user again inputs an invalid choice, say, for example, "c", the error message is again displayed followed by the prompt. Typically, multiple invalid choices which are all displayed will cause the screen to scroll so that the user can no longer see all the parameters which were originally displayed.

Display of Invalid Entries As Parameter Choices

When using the printer profile utility, the user is required to make certain choices with respect to the printer parameters. In a typical example, the screen below might be displayed to allow the user to change the printing pitch. If the user makes an invalid choice, as, for example, specifying the pitch 12 rather than the valid choice b, an error message is displayed followed by the input prompt. In this example, the appearance of the screen would be as shown below. If the user again inputs an invalid choice, say, for example, "c", the error message is again displayed followed by the prompt. Typically, multiple invalid choices which are all displayed will cause the screen to scroll so that the user can no longer see all the parameters which were originally displayed. The solution to this problem is to display only the last invalid choice and prevent the screen from scrolling. Thus, in the example given where a second invalid choice of "c" was made, the "c" goes where the first invalid choice "12" was. This allows the user to always see the possible choices and the last invalid choice, but since the screen does not scroll, the display stays intact for continued reference by the user.
