I don't know of any other Graham there, that's him.
As to why he never told you about it, I couldn't say. The original staff that purchased the printer are no longer there, they left years ago, he now is in charge of it apparantly. They have had it for some time.
I went to Jeff's shed a long time ago at an expo with the college and suggested to the staff they buy it. They did. Since then the staff I had a relationship with have left. Graham is now in charge of it/lumped with it, not sure how he feels about it.
Anyway, it's there. I was able to use it for quite a few projects at no charge initially, but I believe that has changed now.
I was at a party with Graham and a lot of the old staff from the Engineering Dept of Dandy TAFE last week. I worked there for 9 1/2 years.
