Many Windows programs allow designing with different colors and shades of gray, even though the thermal printer only prints in one color: black. By outputting different black
3.4.7 Bar Fonts Tab
NOTES:
∙Most thermal printers have internal support for many different bar code symbo- logies. Most Windows ap- plications are unable to access these bar codes directly. However, it is possible to create an artificial font that represents a bar code, and then this font will be listed and can be selected within any Windows application that supports printer fonts. At print time, the font is converted by the driver into the desired bar code.
∙Some symbologies will have minimum and maximum data lengths, or only accept certain characters. The bar font functionality in this driver will properly filter, format and add necessary characters to bar codes before they are printed.
Dithering - Creating the illusion of different shades of gray by varying the pattern of dots. Close observation reveals that varying the patterns of black and white dots produces different shades of gray. There are no gray dots at all. The more dither patterns that a device or program supports, the more shades of gray it can represent. This screen allows making the following selections for dithering.
∙None. Outputs the sharpest images when printing bitmap graphics that contain only black and white, but no colors or grays.
∙Coarse. Does the best job of printing lots of different shades of gray, but will but will soften the edges of graphic images the most.
∙Fine. Retains greater clarity in higher resolution graphic images than than the “Coarse” setting, but can’t print as many different shades of gray.
∙Line Art. The “Line Art” dithering method uses patterns optimized for printing line art, rather than general purpose images.
∙Error Diffusion. Uses a more complex algorithm to avoid the patterned look of the “Coarse” or the “Fine ” setting.
Intensity - The intensity of the printed label can be adjusted with the slider bar from 0 (darkest) to 200 (lightest). Default value is 100.
Color - the only selection here on the
This Property Page will allow adding, deleting, modifying, importing, exporting, and viewing currently defined bar code fonts. These fonts will be listed in many Windows applications that normally do not support printing bar codes. Although they will not appear as bar codes on the screen, they will print as bar codes. An unlimited number of bar fonts can be created, each of which may have different bar code parameters.
Upon pressing the Bar Fonts tab the screen display below will appear.
