this come just come, i changed on down print as graphic

switched to sumatra pdf

on my list http://d.oga.pl still exist xchange pdf
maybe some day will find older version without bug negative printing

i never used negative, i didnt see any option to do this
if some changed in printer options always changeable temporary

sry to leave this software,
dont need editor 147MB installer, i use only lite software
PDF-XChange Viewer installed 35MB
i must find different small pdf viewer

2.5 b322.10 (dec 13 2018; 09:19:53)
i use pdf viewer as external program (not opening inside browser)
when this bug happened, i changed pdf to open internal browser by firefox

there wasn't any problem with printing

dont from which time, from which version
pdf viewer print in negative
