Led Indicators; Graphic Printing Vs. Printing With Printer's Fonts - Hengstler XPM 80 Operating Manual

XPM 80™ Thermal Printer Family
3.5.10.
There are two LED indicators in the XPM 80™ series printers, located as shown in
Fig. 4. These LEDs are used to signal some status information concerning the XPM
80™ printer. The following is a partial listing of the information supplied.
There are several flashing speeds used in the XPM 80™ 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)
Off
On
Red LED
Please note that much more detailed information concerning the printer's current
state can be obtained by requesting the printer's status via the interface. Please refer
to the XPM 80™ 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 80™ easier for you.
All printers contain a set of commands that will cause the printer to perform different
functions. (For the XPM 80™ family of thermal printers, these commands are documented in
the XPM 80™ 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.
