HOW TO: Determine Printer Status and Print Job Status from Visual Basic

Summary

This article describes how to use Windows application programming interface (API) functions in Visual Basic to determine the printer status or the print job status programmatically. Although an application does not typically have to check the status of a printer before printing, it may be useful to determine the status of a printer or print job programmatically.

Description of the Technique

The term "printer" can refer to a hardware device, a queue, a driver, or even a port. In this article, the term "printer" is defined as a local print queue. The code sample in this article returns the statuses that the operating system reports. This is the same status that the spooler reports, which you can check by watching the local print queue.

For example, to view the queue on a computer that is running Microsoft Windows 98, click Start, point to Settings, click Printers, and then double-click the icon for the printer whose queue you want to view.

NOTE: You cannot communicate directly with the physical printer. You should not have to do this because the operating system must arbitrate access to the hardware.

The sample code in this article examines the local print queue, which obtains information from the port monitor, which in turn communicates with the physical device. For a more detailed description of how this works, see the articles that are listed in the "References" section of this article.

This sample reports the status from the printer and from the jobs, but note that the job status information is generally more reliable for applications. Ideally, you should examine the jobs and the printer statuses separately, and the code should infer the "meta" status of the queue. However, for most uses, your code can rely on the job statuses. Also, this example loops through the jobs and checks and reports the status of each job. This is because your job may follow another job that is reporting a problem, such as being out of paper or getting jammed.

NOTE: The system only checks the status when the system has a job to spool. Otherwise, the queue is considered "ready" because the queue can accept jobs, even if the hardware is in an error state. For example, if the last job that was printed used the last piece of paper, the operating system does not know this until the system tries to print again.

Additionally, although there are many statuses that may be reported, many are not supported in practice. The printer hardware and the port monitor determine which statuses to report. For example, if the printer is out of paper and offline, the status may be reported as "Printing" because that is what the job is trying to do. Therefore, a queue that displays "Ready" does not guarantee that your print job will complete successfully.

This code sample examines only the local queue, which should suffice for most applications. However, connecting to remote printers can become fairly complex. You can have chained queues, in which the port for the local queue is actually another queue. You can have printer pooling, in which multiple printers work from a common super queue. When the architecture becomes more complex, the code to retrieve a meaningful status also becomes more complex, and the usefulness of the status is reduced.

On Microsoft Windows 95, Microsoft Windows 98, and Microsoft Windows Millennium Edition only, you can also examine the PrinterInfo.Attributes field for the bit PRINTER_ATTRIBUTE_WORK_OFFLINE. This state is something that typically occurs because of user action (for example, if the user right-clicks a printer icon and then clicks Work Offline). This state does not occur because of the state change of a print job, although the operating system can force state if the printer cannot be connected to despool a job. In that case, the status is typically reported as USER_INERVENTION_REQUIRED.

  3. Add three CommandButton controls.
  4. Add three TextBox controls to Form1, and then configure the TextBox controls as follows:
    1. Set the MultiLine property of each TextBox control to True.
    2. Size each TextBox to approximately five inches wide and three inches long.
    3. Set the ScrollBars property of each TextBox control to 2 - Vertical.
  5. Add a Timer control to Form1.
  6. Add the following code to the Form's module:
