Abstract

The microcode for a document on demand printer is modified to provide automatic EJECT and LOAD functions, obviating the normal requirement for the printer operator to manually depress the printer EJECT and LOAD keys for each print job. This reduction of operator interaction with the printer, after set-up, to the sole act of tearing off the form on completion of each print job, if desired, facilitates unattended or under the counter operation.

Automatic Eject And Load Functions for Document On Demand Printer Facilitate Under Counter Operation

The microcode for a document on demand printer is modified to provide automatic EJECT and LOAD functions, obviating the normal requirement for the printer operator to manually depress the printer EJECT and LOAD keys for each print job. This reduction of operator interaction with the printer, after set-up, to the sole act of tearing off the form on completion of each print job, if desired, facilitates unattended or under the counter operation.

The Figure shows the present embodiment schematically. It is seen that the printer ejects the printed form up through a slot in the counter where it is accessible for tear off by the operator. It is apparent that in ejecting the completed form to the position where it can be torn off, the following form, or forms, are transported past the printer printing line. To avoid wastage, these forms are "loaded" into the printer. This is accomplished by a reverse feed operation that returns the next succeeding form to print station.

The microcode is modified to generate an "EJECT" function upon detecting the end of a print job (e.g., a Form Feed operation); to EJECT and LOAD the forms a selected further than normal distance to accommodate the increased forms travel from the printer up through the counter; and to generate a "LOAD" function upon detecting the start of another print job.
