SYMPTOMS
When a printer is temporarily out of service because the paper is jammed, no paper is in the paper tray, or the printer is offline, normally a message is sent to the DOS or OS/2 workstation stating that the printer is unavailable to complete the print job. However, quite often a DOS Enhanced workstation will not display the message concerning the unavailability of the printer.



CAUSE
The messenger section of LANMAN.INI contains a parameter called sizmessbuf. On OS/2 workstations, the default value for sizmessbuf is 4096 bytes. On DOS Enhanced workstations, the default value for sizmessbuf is 256. When a message is received whose total size is larger than the message buffer size, the message is dropped. The printer unavailability message can easily exceed the 256 byte buffer size.



RESOLUTION
Increase sizmessbuf to accommodate longer messages. Doubling the default value to a 512 byte buffer should be sufficient for the printer messages. Please note, however, that doubling this value will affect the total available memory to the DOS workstation.
