Hi Maxim, sorry I didn't get back to this yesterday, the time difference is against me

I can see the hatch line thickness difference on screen and when printed yes, I believe this is because there are varying transparencies from when I have been testing printing, but I'm at a loss as to why they are different to mine. The "default" lineweights are all printing thicker than mine also, is this because yours is set differently? Mine is on 5 as I typically like fine line drawings

However the hatches are still all complete when printed on my own printer which is the issue - would it be possible for you to print my original PDF to see if you can replicate please - you will instantly see the problem.

My PDF was generated by the general documentation dropdown setting in batch print as shown on the attached screenshot - is this what you mean?

PS: I have been researching .PC3 and will try duplicating and renaming my printer in settings - my other frustration and cause for delays with this; is that I have s to send every PDF to a friend to print as they are all absolutely fine when printed here

PPS: It's also worth noting that when I export back to 2017 the same issue is present, I have many other 2017 documents using the exact same hatches that all print fine on others printers
