Problems when printing

Hi, I'm a newbie on this software, didn't find my issue in the search of the website (if it exists please point me to it).

the issue is when printing on A0 size or when attempting to export the file.

the file (example 1) is the output for exporting, the file as PDF (after using the print preview to set the ration to 1:2 and the size to A0 and Landscape orientation. the export shows only one file, the 0(Copy0) layer, some elements of other layers are faintly there a almost as trace, but not in a usable status.

the file (example 2) is what i see before the export, i checked if changing the print option of the layers changed anything, only managed to hide the 0(Copy0) layer but not much else showed in export, i expected the order of the layers to play a part in this but since i have no idea how to change the order i couldn't do much.

Deepseek couldn't help me out, or maybe i'm just too slow to get what it means.

An interesting thing is that "export as image" option isn't affected by this, it shows all layers correctly and without issue, which is the way i eventually made do by exporting as image and using a 3rd part software "bullzip PDF printer" to change the file into a A0 size PDF print.

sorry if the writing is a bit confusing, ESL and all that.

Example 2 (what i see)

Hi,
You could try playing with Black/White and line scaling buttons to see if they help, the 2 buttons at the right of "fixed" checkbox in your example2 file.

Also, you could check the default line size of the layers that don't print.

hi, thanks for replying, i was expecting a reply in like two weeks tbh :)

this is the result for changing the Black and White scaling, and trying to apply the scaling, I'm afraid the results aren't better, its just the same but in greyscale.

the result i find most usable so far is that i export as image, run the (image now) file through the bullzip software to fit into an A0 format and go print it, its pretty good for my use case but i don't know if it can be a long-term solution for someone using this professionally.

the result example 3 (named example 6 because i save several times)
