First, scan your handwritten signature and save it in PDG format. Pay attention to the clean background, preferably white.

Then insert your signature into excel, click on the picture, and the picture toolbar will appear. Click on the color in the upper left corner and count from bottom to top. The second command is to set the transparent color, click the activation command, click once on the picture, and the background of the picture will be removed. If it is a complex picture, please use the Delete Background command in the upper left corner, or use other software to delete the background. Adjust the size and position of the picture and you can print it.

If you can't see the printed object in the print preview, click the picture, right-click, Properties and check the printed object so that you can see the picture when you print the preview again.
