ESC U {n}
In IBM, if the parameter {n} is equal to {odd number}, this sequence causes
subsequent data to be printed monodirectionally, from left to right, instead of
bidirectionally. To cancel monodirectional printing and return to bidirectional
printing, {n} must be equal to {even number}..In EPSON, if the parameter {n} is
equal to {1}, tis sequence causes subsequent data to be printed monodirectionally,
from left to right, instead of bidirectionally. To cancel monodirectional printing
and return to bidirectional printing, {n} must be equal to {0}. When the printer is
turned on, however, printing is performed bidirectionally.
ESC <
This sequence causes subsequent characters to be printed from left to right
(monodirectionally) for one line only. It is cancelled by a CR.
ESC @
This sequence causes the printer to be initialized. This command, inserted in the
input buffer, will be executed during processing, so that data preceding this
command will be printed according to previous setting. This code goes back to
current Printer Setup setting, that is, the most recent values set, cancels any print
attributes that have been set, initializes the printer carriage, resets the column
counter, sets the horizontal tabulations every eight columns, clears all vertical
tabulations set. Only the selection of Draft or Quality printing and the selected
character generator are maintained.
ESC [ K {n1}{n2}{init}{id}{parm1} {pamr2}
This command causes the printer to reset to its initial status:
Sets and cancels monodirectional printing.
1B 55 {n}
27 85 {n}
Prints characters from left to right for only one line
(only EPSON mode).
1B 3C
27 60
Re-initializes the printer (only EPSON mode).
1B 40
27 64
Sets the initial condition (only IBM mode).
