Robert asked -
"Do you have any trouble getting things in and out of the washer to the end of the sink?"
Good question! I just recently added another level to the shelf unit that supports the print washer in question. I did this to raise the bottom of the washer higher than the bottom of the sink, so that I can siphon the water out of the washer (this 11x14 model has no drain). Raising the print washer has put the top of it nearly at chin level - higher than ideal, certainly, but still workable.
When I get around to printing 16x20, loading and unloading the larger print washer in that location my be a real handful, and I'll need to have to have a usable procedure worked out. Perhaps a small stepstool will be all I need.
