Anyone familiar with this? Is it some Acrobat bug?edit. ok, now I see, hi-res is different from low-res, it´s redistilling the pdf. Um..

Set lower resolution for printing in security setting - 150dpi.It´s strange error, which I am also trying to solve now. 150dpi is working fine with ´Printing allowed´, but I need to set hi-res and obviously with the same error result (postscript error).
