The automated print media stacking apparatus makes use of a passive guide in the bottom of the stacking bin to automatically initiate the folding operation on printed continuous feed fan fold print media (e.g. - paper) and to precisely refold and stack the printed media as it is output by the high speed line printer. The automated print media stack apparatus includes a slotted forms refold tray that is located at the bottom of the stacking bin. The slotted refold tray includes a slot located in the center thereof for automatically receiving the leading edge of the first sheet of print media that is output by the high speed line printer. An associated media puller is used to insure the proper positioning of the leading edge of the first sheet of print media into the slot in the paper refold tray.

In a data processing system which includes a host computer connected by a channel interface unit through an input/output interface and control unit to an input/output device, commands and data associated with the commands are received in a buffer and first checked to determine whether the command has any pertinent data. If such check reveals that there is no pertinent data associated with a given command, that command is changed to an immediate command. Otherwise, the command is given a pointer in the buffer which prioritizes the order in which it will be carried out. Where a command is determined to have no pertinent data associated with such command, and a previously buffered command still in the buffer has pertinent data associated therewith, consolidation of the command immediate with the previously buffered command is carried out in order to improve efficiency of the input/output device.
