Summary:
Printing a lot of reports at once or if Citect is busy while printing reports may cause Citect to crash. 

Solution:
This problem is due to an error in the allocation of spool buffers. The number of buffers allocated at startup has been increased from 4 to 32 to fix this problem. Also if the number of buffers increases above this limit you will get a hardware alarm on the device and Citect will not crash. The limit of the number of spool buffers can be changed by the parameter

[Device]
PrinterSpoolBuffers=
Min: 4
Max: 128
Default: 32

CIT has confirmed this to be a problem in Citect for Windows versions to 5.00. This problem has been fixed in version 3.40/4.20 Service Pack J and 5.00 Service Pack E.
