Digital BW, The Print

I hope this is not too far off topic.
I need a printer capable of printing A2 size CAD engineering drawings 
in B&W, even better if it can handle A1 size paper.   Having reviewed 
the price of new equipment I am wondering if anyone is planning to 
upgrade soon and is looking to sell their old machine.   Please email 
me off-group if this is of interest.
