Do I understand correctly that you want to print several copies of the same PCB onto one sheet? * Did you know that you can get professional quality PCBs made at very low cost directly from EasyEDA? This might be a better option if you want to make several PCBs from the same design. :)

When you order your PCB, you can use https://easyeda.com/Doc/Tutorial/PCBOrderFAQ#Panel-by-EasyEDA

Yes, I want to print several copies of the same PCB onto one sheet. How it is possible to do this in the EasyEDA interface? I need only print in this stage, not to order.

in this case, you can copy and paste, the adjust.

As Dillons says, 1. Open your PCB in the PCB editor; 2. Open a new PCB Editor window (to avoid overwriting your original layout); 3. Copy and paste the whole layout into the new window as many times as you want; 4. adjust the position in the window as required; 5. Turn off the visibility on the` Ratlines` layer; 5. Print... Here's an example: https://easyeda.com/andyfierman/Multiple_PCBs-30a6cd6d9b2148ecb596531bc7bd68e9

Another (better) possibility is to `Export...` the PCB layout as a .PNG format image then, in the browser window that opens, right-click on the image and select `Copy image`. Then paste the copied .PNG image into a sheet in LibreOffice Writer or Draw and then export that as a .PDF.

Andyfierman, thanks. I will try your methods. But it is strange that the interface cannot provide any possibilities for preprint setup, such as copies number and positioning on the sheet.
