I read other answers about scaling problems when printing with Eagle and I don't think my printer is completely at fault.
I ran some tests. I tried printing a PCB (about 8 inches by 4 inches in real size) with the following settings:
- Landscape, and letter size paper
- Portrait, and A4 size paper
- Portrait, and letter size paper
All other printer settings are the same in all tests.
When I printed (I checked the caption option), the sizes are different each time, and I think the sizes are denoted by the letter "f" in the caption.
The caption format printed is as follows:
"XX/XX/XXXX TT:TT:TT f=S.SS /path/to/file.brd"
where XX/XX/XXXX is the current date, TT:TT:TT is the time and f=S.SS which I believe is the scale factor. The S.SS reported 0.83, 0.96 and 0.93 respectively even though I set scale to 1 in software.
Is there some simple workaround to this? could I somehow force F to be 1?
