Thank you for good improvement ideas.
About the problem of laser printing of large metal areas. I wonder if anyone has used color printer to overcome the issue? If I would use some kind of grid of different toner colors, then I don't actually print single large metal area. According to my understanding, color laser printer just has several laser printers in serial.
I haven't try to make my own fixing ink from toner and acetone. I have used silver paint pen to fill some holes when needed. This pen will dissolve some of toner. I think most of my holes are very small and there are so many, that manual fixing would be huge effort. Press n Peel film has this blue stuff, which I think will protect toner a bit. Acetone will dissolve blue stuff as well. Anyway, I have to try.
Lexmark MX310 seems to be discontinued. Lexmark ink seems to work.
Anyone used Xerox?
Based on this site, Xerox is the best:
