Print Jobs from MAC OTI Clients May Hang in WinNT Print Queue

SUMMARY

When you print to a Windows NT Server with Services for Macintosh installed from an Apple Macintosh client running (OTI) Open Transport Protocol, the print jobs will hang in the Windows NT print queue for up to 30 minutes. The print jobs hang indefinitely in a "spooling" state.

This problem is caused when you send a print job to Windows NT from a Macintosh client running OTI. When the Macintosh client finishes sending the job to Windows NT, the LaserWriter driver sends out its PAP EOF and ATP EOM, then it sets up a data structure and waits for the transaction release (TRel) coming back from the Windows NT Server. The result is that the client never sees the TRel and never breaks down the connection before it receives an OpenConn PAP request. The TRel is coming back from Windows NT before the LaserWriter driver is ready to handle the TRel, resulting in the job staying in a spooling state on the Windows NT Server.
