I'm having the same problem in a application I'm developing. Around 1 out of 50 print attempts result in a exception from Crystal Reports with the message mentioned above. We're using Zebra TTP2030 thermal printers but I'm fairly sure this is not hardware related. The error is in Crystal Reports or the code using crystal reports. My current theory is that it's related to some kind of improper use of threading and Crystal Reports objects in the code. I'm rewriting most of my code relating to printing now making sure there is no possibility of different threads accessing the same objects. I noticed also that Crystal Reports is filling up the temp dir with .rpt and .tmp files and first I thought this was the cause but even when making sure the temp-files are cleaned by my code I still get this. It's a pain to debug this as it seem to happen so rarely. This is a software issue. I’m having the same problem in a application I’m developing.

Maximum time after print first copy it stops and shows the error message as I told before. Some time it is happening after print 2 copy print out. So I think it is not the programming issue.

This could be a programming issue considering it happened on 4 machines. When do these problems occur and how often? This could be a programming issue considering it happened on 4 machines.

Same problem is occured in 4 machines. I used the thermal printer CITIZEN CT-S310 with auto cutter. Yes I checked it. Same problem is occured in 4 machines.
