Can UP 2000 printer work with R and L justified stencils?

Electronics Forum | Mon Jul 31 16:33:48 EDT 2006 | G.P.

I think he meant stencils where the print pattern is front, left, or right justified on the stencil itself as opposed to being centerred. Is that what you meant. It can be done on DEK printers, but it has been several years that I worked with an MP
