This command deletes all data in the print buffer and activates the
values selected in the print menu. Functions set via the control pa-
nel are reset. This procedure is also called initialization. If in the
menu Reset Inhibit is set to Yes, the command is not executed.
Numerous software packages send a reset command to initialize
the printer before or after printing. In this way it is ensured that
values used in a previous printing process are not inadvertently
used for a subsequent print job.

printing
To optimize throughput, printing of lines normally takes place al-
ternately forwards (from left to right) and backwards (short line
seeking , bidirectional printing). In order to improve the alignment
of lines lying underneath one another you can stipulate with this
function that each line be printed starting from the left margin (uni-
directional printing). You should use this option when precise ver-
tical alignment of the individual lines is desired (bit image gra-
phics, IBM graphic characters, tables).
The print speed is somewhat reduced with unidirectional printing,
as the print head after printing a line is reset to the left margin to
start the next line there. This function can also be activated for prin-
ting bit image graphics via the Graphics menu item.

printing for one line
This command resets the print head to the left margin (print start
position) to print the line following this command. The effect of the
command is unidirectional printing for one line. Printing then con-
tinues bidirectionally, unless unidirectional printing is selected.
