Since you posted this as a ticket as well I'll send the same answer from that ticket for this question:
At this time TeamDynamix doesn't have a specific "Print" option for KB articles. This would have to be a feature that might need to be added.
You could instead try copying the content into a Word document and printing that out if a formatted version were needed. Otherwise the browser print option is the only available route to get KB content to print out currently.
Let me know if you have any questions about this.
