I'm sorry you are having trouble. I have a few questions for you:
1) Are you using the most recent version of SmartOffice (2.3.10) and if not, can you upgrade?
2) What type of document was it, and what format? (i.e. Word DOC or DOCX; Excel XLS or XLSX)
3) Can you tell me more about what you mean by "...started s a prime saying print error..."?
4) Did the printer appear normally in the application when you tried to print?
5) Can you send me a copy of the problem document? If you don't want to publish it on the forum, I can send you my email address privately.
