1. Open the control panel-Printers and Faxes

2. Right-click your printer-Properties

3. Click the corresponding machine icon in General and select the printing preference

4. Switch to Paper/Quality > > Point advanced > > Check what kind of paper is used in the paper specification and write down the name

5. Tips:

Control panel-right click on the blank space for printers and faxes (don't click on the printer)

There is a server property > > After clicking > > Find the name of the paper in the format, and check the format description (size) below. If you can modify the size setting of the paper, slowly modify the height to a suitable value, and you will have to experiment it yourself slowly.

If you can't change it, choose to create a new format, fill in a table name, and then fill in the required size. After saving, come back to the place where you just checked the paper used by the printer and replace the paper with the paper you just created.
