FS#1929

Drawing and PrintPreview are consistent, but printout differs : rectangle missing (bottom right), line missing (bottom green line) - see att. Error can be reproduced, after saves and restores.
A VERY elementary WYSIWIG-problem....

Please check your line weights. Lines with weight 0.00mm might print so thin on your printer that they are simply invisible.

If you cannot solve the problem, please attach your DXF / DWG file.

Sorry, didn't see this response - I added the same subject again (#1929).
The line thickness cannot be the problem, as there is the thick, green line (same type as the one shown correctly)...

I cannot confirm that. The rectangle at the bottom right is on layer "Defpoints" with line weight set to "By Layer".
Layer "Defpoints" has lineweight "Default". Layer "Defpoints" is actually a file format internal layer. I'd recommend to not use that at all and create your own layers instead.

Fix: move the rectangle to a different layer with a line weight set to e.g. 0.13mm.

Thanks !

But, still - how can a preview as expected be transformed to a 'wrong' printout ?....

A line with a width of 0.00mm is shown "as thin as possible". On a computer screen that's one pixel which is still very much visible. On paper that's the smallest printable line which on modern printers is almost invisible or even completely invisible. You can read more about this at: https://en.wikipedia.org/wiki/Dots_per_inch

Closure comment

Likely usage problem (line too thin).
