These two members differ in that the Status member is a bit field of states that contains predetermined values, while the pStatus member is a pointer to a string that could contain just about anything. Both members contain status information of a print job reported by the port monitor. The JOB_INFO structures contain a Status member and a pStatus member.
In addition, the most meaningful information may be reported in the status members of a JOB_INFO structure for that particular print job because some port monitor will have set these values directly. This is the only time the state of the printer is reported by the port monitor. There is one fundamental premise that must be true to determine the state of a physical printer: the Spooler must be attempting to send a print job to the physical printer.
Determine the state of a physical printer It isn't considered an error reportable to the application that is allowed to complete the spooling of the print job successfully. Such a circumstance is considered an error state in the operating system that must be addressed by the user. The operating system considers the Printer ready to accept print jobs even if, for some reason, it can't complete delivery to the physical printer. This is a valid assumption even if the physical printer is in an error state such as off-line. In this state, the Printer is assumed ready to accept print jobs. The Spooler, in turn, propagates reasonable error information to the Printer Queue.Ĭonsequently, a system Printer reports no status when the Printer queue is empty. If some error occurs in this process, the error is reported by the port monitor and recorded in a print job's status information. Instead, the state of a physical printer determines the success of a print job at the time it's despooled over the port monitor. The Spooler doesn't query for the state of a physical printer to which a Printer is connected. It's the job of the port monitor to report those errors. This connection, and the physical printer, are where errors occur. In the case of bi-directional printers, the port monitor would be responsible for transferring data to and from the physical printer. The port monitor is the interface to the physical printer at the down- stream end of a system Printer and is responsible for transferring the data of a print job across whatever connection exists to the physical printer.

The I/O path for a Printer consists of several layers of system code culminating with a port monitor.

The printer driver is the interface to the Printer that is used by applications to create print jobs via printer DCs.

It's managed by the Print Manager or the Printer folders in the Windows 95-style user interfaces. The most visible part of a Printer is a print queue. The operating system treats a physical printer as merely the destination of a print job generated by and passed through a system Printer, referred to in the rest of this article as a Printer. At all other times, when that printer isn't despooling and reports no state information, the printer is considered to be ready and idle.Īs referred to by the Win32 API, a printer is comprised of the printer driver, the print queue, and the input/output path to the physical printer. The status of printers and print jobs are updated by the Win32 Spooler during the despool of a print job. Original product version: Win32 Spooler Original KB number: 160129
