I have an HP Laser Jet M452dw and have been using it to print clock dials. I use Affinity Designer on a Mac to create the dials using vector and pixel images. A typical dial will have 2 concentric circles of .1pt. to .3pt. Those circles have been printing just fine up until recently, when 2 very small portions of the circles print as broken lines. Those broken lines always show up 180* from on another, between 1 & 2 and 7 & 8 on the dials. Can anyone tell me what the problem is?
