The fictive printer emulated by textprinter can print in landscape mode, set the character size, print bold, underlined and/or italic text. And (a feature that no real printer had) it can print pictures from a .jpg file.
A control sequence is always started by ESC, in Python code you would write "\033" or "\x1b".
| ESC "c12" SPC | select 12 cpi |
| ESC "b1" | activate bold font |
| ESC "b0" | deactivate bold font |
| ESC "i1" | activate italic font |
| ESC "i0" | deactivate italic font |
| ESC "u1" | activate underlined font |
| ESC "u0" | deactivate underlined font |
ESC means : a byte of value 0x1B (Escape)
SPC means : a byte of value 0x20 (Space)
