The Robotron 6313 printer was a 9-pin dot matrix printer manufactured by the VEB Robotron (East Germany).
What made it special and worth mentioning in the CPC-Wikipedia is the fact that it could be DIP-switched to be 100% compatible with the Amstrad/Schneider NLQ401, that means it could print the whole CPC character set and understood the code sequence to switch the 8th bit.
In Western Germany it was sold under the names
Präsident 6313
or
Europrint FT80X

Control codes (additional to IBM PC control set)
ESC = = Select switched character set
Encoding:
- CHR$(27); "=";
Function:
- This command selects the printable characters that equal the 7-Bit characters from CHR$(1) to CHR$(127).
- The reception of the command ESC = results in bit 8 to be regarded as 1 for all received characters.
NUL = Unselect switched character set
Encoding:
- CHR$(0);
Function:
- The reception of the command NUL results in bit 8 to be regarded as 0 for all received characters.
