SYMPTOMS

In Microsoft Host Integration Server, host print sessions that have the Request Definite Response option enabled may stop responding (hang). After this problem occurs, you cannot send any new host print jobs to the host print session.

CAUSE

This problem occurs because the print server does not send a response to the host system when a print job is completed if the time that is between print jobs is more than the timeout that is configured in the After Job Ends, Delay Closing Printer option in the print session. Because the host system is waiting for a response that indicates that the previous job has completed printing, additional print jobs cannot be sent to the print session. This behavior causes the print session to stop responding.

RESOLUTION

WORKAROUND

To work around this problem, disable one or both of the following configuration options in the print session properties:
  • Request Definite Response
  • After Job Ends, Delay Closing Printer

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was corrected in Microsoft Host Integration Server 2000 Service Pack 2.

MORE INFORMATION

In SNA Server 4.0 and earlier versions, the host print service (Snaprint.exe) opens all defined printers that are used by the configured host print sessions when the service starts. The After Job Ends, Delay Closing Printer option was added in Host Integration Server 2000 to optimize performance and system resources. If the printer is always available, system resources such as printer handles are consumed. However, if the printer is constantly opened and closed with each print job that is sent, performance suffers. By setting the After Job Ends, Delay Closing Printer timeout option, the printer will remain available for print jobs that are sent close together to improve performance, and the printer will close during non-busy times to free resources.

By default, the After Job Ends, Delay Closing Printer option is enabled and the timeout is set to 10 seconds on Host Integration Server 2000 and Host Integration Server 2004.

The problem that is described in the "Symptoms" section occurs when the Request Definite Response and After Job Ends, Delay Closing Printer options are both enabled on a host print session. If multiple host print jobs are sent to the host print session and the delay between each print job is less than the timeout that is specified in the After Job Ends, Delay Closing Printer timeout option, all the print jobs are printed. Additionally, the host print service sends a response to the host system to indicate that each job printed successfully. The Request Definite Response option provides this functionality.

If multiple host print jobs are sent to the host print session and the delay between one or more of the print jobs is more than the After Job Ends, Delay Closing Printer timeout option, all the print jobs are successfully printed. However, the host print service does not send a response to the host system for the print job that was sent after the After Job Ends, Delay Closing Printer timeout expired. This behavior causes the print session to stop responding because the host system will not send any additional print jobs to the print session while it is waiting for the response to the previous print job.
