can also be used when the system works with an internal generator.
As the printer cannot control the frequency of pulses generated by the external encoder, the
allowable settings can be exceeded and the overprint deformed - see section
6.3.10 Some
vertical rows of overprints are spaced widely
. In order to avoid such deformation, the timing

frequency should be chosen in such a way that the settings offered by the ROWS SPEED
command do not exceed the maximum print rate. The rate (given in m/min) depends on the font
applied and on print parameters such as

4.6.3. Defining Maximum Print Rate for a G
Irrespective of whether the printer works with an internal generator or a shaft-encoder, you should
follow the procedure given below in order to define the maximum print rate for a text file with selected
fonts (also called generators or character matrices):
1. In the TE

2. Use the PRINTING PARAMETERS command from the PRINTING submenu to set the required
print parameters, especially the Speed , Interleave and Resol. dot/cm parameters and also to
set:

6. Press the

key and hold it down until the value of the Cnv spd m/min parameter stops
increasing. After the maximum travel speed has been achieved, this value stops increasing. This
is the maximum print rate for the selected fo
