Abstract

When using a printer of a Personal Computer (PC) in a typing application in which a typist uses a keyboard of the PC to type, automatic loading of the paper occurs without any space, line feed, or character print occurring. A typist normally desires to load a sheet of paper before starting to type to make sure that it is aligned properly. With a PC printer having a sheet feeder which automatically loads paper in response to the first character, space, or index received, the typist cannot load the paper manually. Since the typist normally relies on a good rhythm to type effectively, loading of the sheet of paper on the first typed character is not desirable.

Initiating Paper Load From a Personal Computer to a Printer in a Typing Application

When using a printer of a Personal Computer (PC) in a typing application in which a typist uses a keyboard of the PC to type, automatic loading of the paper occurs without any space, line feed, or character print occurring. A typist normally desires to load a sheet of paper before starting to type to make sure that it is aligned properly. With a PC printer having a sheet feeder which automatically loads paper in response to the first character, space, or index received, the typist cannot load the paper manually. Since the typist normally relies on a good rhythm to type effectively, loading of the sheet of paper on the first typed character is not desirable. Thus, when using the printer in a typing application, the sheet of paper can be loaded in the printer from a sheet feeder without printing the first typed character or creating a space or a line feed. This is accomplished by the Printer Communication Routine program sending a Print Low Graphic Escape Sequence to the printer and specifying the character to print as null (00). This causes the printer to enter its print routine to load the paper if such is necessary. After the paper is loaded, the printer checks the character to print. Since a null is ignored by the printer, the printer ends up with the paper loaded but having no effect on the status of the printer. Therefore, the typist can load the paper to typing the first char...
