Open a Math document, choose LibreOffice - PreferencesTools - Options - LibreOffice Math - Settings.

## Tùy chọn in

### Tuổi tác

Specifies whether you want the name of the document to be included in the printout.

### Chuỗi công thức

Specifies whether to include the contents of the Commands window at the bottom of the printout.

### Viền

Applies a thin border to the formula area in the printout. Title and Formula text are only set down by a frame if the corresponding check box is active.

## Định dạng in

### Kích cỡ gốc

Prints the formula without adjusting the current font size. It is possible that with large formulas a part of the command text is cut off.

### Vừa kích cỡ

Adjusts the formula to the page format used in the printout. The real size will be determined by the used paper format.

### Co giãn

Reduces or enlarges the size of the printed formula by a specified enlargement factor. Type the desired enlargement factor directly in the Scaling control, or set the value using the arrow buttons.

## Tùy chọn khác

### Bỏ qua ~ và ' ở cuối dòng

Specifies that these space wildcards will be removed if they are at the end of a line. In earlier versions of LibreOffice, adding such characters at the end of a line prevented the right edge of the formula from being cut off during printing.

### Embed only used symbols (smaller file size)

Saves only those symbols with each formula that are used in that formula. In earlier versions of LibreOffice, all symbols were saved with each formula.
