I'm still in the process to understand what is helpful to Stack Overflow from what isn't. I know that self-answered question is a good thing when it's done the right way. Today, this question https://stackoverflow.com/questions/17710879/java-wont-print-on-lexmark-c544-printer shows up in my feeds.
This question has been answered by the asker recently, but I was wondering if this is a good self-answered question?
For posterity's sake, here is the full text of the answer (now deleted):
For anyone who is interested, I never found the problem. We ended up swapping the printer out with another one that does work. If anyone else has this or a similar issue, please message me if you found a cause/solution.
The answer, in its current format, looks to me like a simple update to the question, not like an answer. It's only stating that they haven't been able to solve the issue, and they have to use a workaround. He is also requesting any useful information if someone is having the same problem. Is this kind of answer useful?
