How To set the font size more bigger

[kenchu1178]

WriteLine_Big only print X2 size , how to print X3 or X4 font size text?

[fgroupindonesia]

have you figured it out?

As far as I remember the ESC-POS protocol only defines a x2 font size command. A workaround is to use an Image/Bitmap object from the .Net framework and draw your on text inside it, then to print the bitmap image.
