Filed:

Apr 17, 2000

Appl. No.:

09/550669

Inventors:

Karen L. Harrison - Longmont CO, US
Charles David Johnson - Boulder CO, US
Larry David Teklits - Loveland CO, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 15/00
G06K 1/00

US Classification:

358 115, 358 19

Abstract:

The present invention efficiently directs the flow of print jobs and efficiently controls the spooling and printing of print jobs. The multiplexer system analyzes jobs received from client systems through print channels. The multiplexer determines the attributes of the incoming job and the attributes associated with the print channel. If the attributes of the print job and the attributes of the print channel dictate an output path (either MUST PRINT or MUST SPOOL), then the multiplexer examines the state of the selected path. If the designated output path (printer or spooler) is busy, then the multiplexer decision is to signal a Stop_Flow to the print channel. The print channel is signaled to Start_Flow at a later time, when the output path becomes available. If the attributes of the print job and the attributes of the print channel do not dictate an output path, then the multiplexer examines a User Output Selection setting to control spooling and printing of print jobs.

International Classification:

G06F 9/46
G06F 15/00

US Classification:

718103, 718100, 718102, 358 115, 358 116

Abstract:

A system, apparatus and method for dictating the order that print jobs received over multiple data channels are printed. A priority value is assigned to each data channel that receives print jobs. The priority value of the data channel is imparted to each of the print jobs received via its respective data channel. The relative priorities of the print jobs is determined, and the print jobs are printed in an order corresponding to their relative priority values.

Filed:

Sep 16, 2005

Appl. No.:

11/228782

Inventors:

Karen Harrison - Niwot CO, US
Charles Johnson - Boulder CO, US

International Classification:

G06F 3/12

US Classification:

358001150, 358001130

Abstract:

Provided are a method, system, and program for processing requests for data sinks in a logical printer. A request is received to process a print job from one of a plurality of protocol components. A determination is made of one of a plurality of data sinks for the print job and whether the determined data sink is available. A return code is returned to the component initiating the request. A data sink available message is returned to the component initiating the request in response to determining that the determined data sink is available after returning the return code. Additional asynchronous operations are performed before returning the data sink available message.

International Classification:

G06F 1130

US Classification:

702186, 710 15, 710 46

Abstract:

The present invention provides a method and apparatus for adjusting an interval of polling a peripheral device (e. g. , printer) for status information, as based on the presence of a predetermined condition. In one embodiment of the present invention, short polling intervals are used to poll a peripheral device when a station (e. g. , computer system) is not receiving adequate and/or reliable notification of interrupts/alerts that occur at the peripheral device. Long polling intervals are used to poll the peripheral device when the station is receiving adequate and/or reliable notification of interrupts that occur at the peripheral device.
