The issue was replicated in QA system R12.1 build # 404 and it appears to be related to the bug [#3060].

The scope of this issue has changed from initial investigation. It turns out to only be affecting MDS / Lifelabs (We've confirmed successful printing of CML labs at the client site.)

Steps to replicate:

• Upload a Lifelabs lab result
• Click Print on the lab result
