To avoid scaling when printing, you can take the following steps:

1. Use appropriate software: Choose software that supports scaling-free printing, such as Adobe Acrobat or Microsoft Word. These software often have print settings options that allow you to control the scaling when printing.

2. Adjust print settings: In the print preview or print settings interface, find the zoom option. Make sure the zoom is set to 100% or actual size. This ensures that the stamp prints at its original size and is not scaled.

3. Check the printer settings: Make sure the scaling option in the printer settings is turned off. Some printers may automatically scale printed content to fit the paper size. You can find and turn off this feature in the printer settings.

4. Use the correct paper size: Select the paper size that matches the electronic seal size for printing. If a smaller paper is selected, the electronic seal may be forced to scale to fit the paper size.
