10.0 Fonts and the Print Command

Your ezLCD-3xx comes with a selection of different fonts pre-installed. Type the command 

PLAY 

FONTS 

into your terminal program to run a macro that displays the factory installed fonts in their 

available sizes. The number designation in the font name refers to the height of the font in pixels. 
Therefore, the font 

SANS48 

is 48 pixels tall when displayed on the screen of the ezLCD-3xx.

The ezLCD-30X font converter for windows will allow you to create and customize new ezLCD fonts 
from TrueType and OpenType fonts. It is available for free download at 

http://www.earthlcd.com/ezLCD-301.

To set the current font, type the command 

FONT [font] 

into your terminal program, where 

[font] 

is the 

name of the font. It is not necessary to include the font suffix (.ezf).  Only *.ezf can be used.

To test your font, type the following into your terminal program:

XY CC 

‘goto the center of the screen

FONT NEURO72

‘select your font file to use

PRINT “HELLO” ‘display the string to screen

The word 

HELLO 

will appear in the center of the screen and display in the 

NEURO 

font 72 pixels 

tall. The 

PRINT 

command always displays text on the screen of the ezLCD-30x at the current XY 

position. When using the 

PRINT 

command, be sure to place double quotes around the text you want to 

appear. 

In addition to printing at the current XY position, text can also be positioned automatically to 9 
positions relative to the current XY: LT (Left Top), CT (Center Top), RT (Right Top), LC (Left Center), 
CC (Center Center), RC (Right Center), LB (Left Bottom), CB (Center Bottom), RB (Right Bottom). 

Note:

 To understand this command visualize your text string as a bitmap or box with characters in it 

and this command is positioning the box. Default position is LT.  To use this feature, enter the position 
information at the end of the 

PRINT 

command. For example, we can set the current position to the 

center of the screen (XY CC) and then print the text using text justified to the center (PRINT “Hello” 
CC):

XY CC ‘set current position to center of screen

PRINT “HELLO” CC ‘print to screen with CC option
