# Preferencias

The GHex Preferences dialog is divided into two groups:

- Display, which pertains to what you see on-screen, and;

- Printing, which only affects how hexadecimal files will be printed on paper, if GHex's printing features are utilized.

## Visualizar

### Font

This allows you to select a font of your choice for the hex/ASCII editor only.

### Dark Mode

This allows you to manually prefer the dark style.

By default, the Use system default checkbox is enabled, uses your system-wide default for preferring a dark style, which disables the Dark Mode switch from being turned on or off.

By de-selecting this checkbox, you may toggle the Dark Mode switch on or off to manually prefer or not prefer a dark style. Toggling this switch will take immediate effect, so you should be able to see instantaneously which style you prefer for GHex.

If you want to go back to the system default, simply check the Use system default checkbox back on.

### Hex Group Type

This allows you to choose how data will be grouped in the hex pane of the editor.

See Hex data grouping for more details.

## Imprimir

### Fonts

This section allows you to choose the fonts you would like for hex printouts.

Data font will apply to the content of your hex document (ie, hex and ASCII digits).

Header font will apply to the header on your printout, which will show the document title and page number.

### Shaded rows

If Print alternating shaded rows is selected, your printout will have alternating rows of your hex and ASCII data printed out with a shaded grey background to make reading each row easier.

Please note that this may use more printer ink/toner than leaving it disabled.

Span across lines allows you to customize how many lines will be shaded, followed by not shaded, on a repeated basis. Again, this is simply for ease of reading. If you want shaded rows but are not sure what to specify here, leaving it as the default, "1", should be fine.
