3.5.8. LED Indicators
There are two LED indicators in the XPM 200HR™ series printers, located on the
opposite side of the controller board near the USB connector. These LEDs are used
to signal some status information concerning the XPM 200HR™ printer. The
following is a partial listing of the information supplied.
There are several flashing speeds used in the XPM 200HR™ printer LEDs. These
are:
Slow: 0.5 Hertz (LED is “on” for one second and “off” for one second)
Medium: 1 Hz (“on” for .5 seconds and “off” for .5 seconds)
Flicker: 10 Hz (“on” for 50 ms and “off” for 50 ms)

to the XPM 200HR™ Emulation Command Set Reference D 690 004 for details.
3.6. Graphic Printing vs. Printing with Printer’s Fonts
One area that causes frequent confusion with regard to printers in general is that of graphic
printing versus printing using the printer’s internal fonts. An explanation here may help clarify
this and make application of the XPM 200HR™ easier for you.
All printers contain a set of commands that will cause the printer to perform different
functions. (For the XPM 200HR™ family of thermal printers, these commands are
documented in the XPM 200HR™ Emulation Command Set Reference, P/N D 690 004.) The
functions are very diverse and there are no standards for what these functions may be. This
allows printer manufacturers to innovate and build unique features into their products. These
commands are often referred to as the printer’s “Native Commands”.
A printer’s Native Commands are of many different types, but a few are of particular interest
to us here. One is the family of commands for printing graphics. It is these commands that
allow pictures and other graphic images of any type to be printed.
