Control Codes in the Text Mode With the MX-80 Type II, two standard operation modes are available. One is the Text Mode which prints corresponding characters on normal ASCII coded inputs and the other, the Bit Image Mode which permits printing of pictures and images in dot configurations. The Text Mode is described in this section while the Bit Image Mode is covered in the following section. The MX-80 Type I I has been designed as a terminal unit capable of various software controls. When control codes are transferred to the Printer, respective functions governed by these codes such as form feed, line feed, etc. are executed immediately. In order to permit the Printer to fully exhibit these functions, careful reading and thorough understanding of the following control codes are recommended. In this section, first the control codes in text mode are classified into groups. These two modes are not fully independent of each other in that parameters set in the Text Mode are also effective in the Bit Image.

3. Control Codes in the Text Mode
With the MX-80 Type II, two standard operation modes are available. One is the
Text Mode which prints corresponding characters on normal ASCII coded inputs
and the other, the Bit Image Mode which permits printing of pictures and images in
dot configurations. The Text Mode is described in this section while the Bit Image
Mode is covered in the following section.
The MX-80 Type I I has been designed as a terminal unit capable of various software
controls. When control codes are transferred to the Printer, respective functions
governed by these codes such as form feed, line feed, etc. are executed immediately.
In order to permit the Printer to fully exhibit these functions, careful reading and
thorough understanding of the following control codes are recommended. In this
section, first the control codes in text mode are classified into groups. These two
modes are not fully independent of each other in that parameters set in the Text
Mode are also effective in the Bit Image.
