Print Conflicts Between Remote and Local MS-DOS-Based Apps (96131)

MORE INFORMATION

Because Print Manager does not control local MS-DOS-generated print jobs and MS-DOS-based programs usually do not close printer ports when their print jobs are complete, the redirector must use the MS-DOS-based application's idle time to determine when to print the remote print job. In Windows for Workgroups version 3.11, this value is specified using the PRINTBUFTIME= statement both in the [network] section of SYSTEM.INI and in the [ifsmgr] section of the SYSTEM.INI file on the client machine. The entry in the [network] section controls network printing timeout using the real-mode redirector (outside of Windows), while the entry in the [ifsmgr] section controls network printing timeout using the protected-mode redirector (within Windows). By default, this value is set to 45 seconds. NOTE: Windows for Workgroups Setup does not add the [ifsmgr] section; this section may have to be added manually.

If the above situation occurs, you are warned that a potential device conflict exists, and, if you continue, the printed output may be incorrect or garbled. The local (print server) print job goes directly to the port, breaking up and potentially interrupting the remote print job.

If you have a shared printer on your machine, do not override a device conflict warning. You may be able to work around this problem by setting PRINTBUFTIME= to a lower value (such as 10 seconds).
