[[Image:Robotron.jpg|thumb|Robotron K6313]]The Robotron 6313 K6313 printer was a 9-needle 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.

<b>Control codes (additional to IBM PC control set)</b>
<br>
ESC = = Select switched character set
<br>
Encoding:
:CHR$(27); "=";
<br>
Function:
:This command selects the printable characters that equal the 7-Bit characters from CHR$(1) to CHR$(127).
:The reception of the command ESC = results in bit 8 to be regarded as 1 for all received characters.
<br>
<br>
NUL = Unselect switched character set
<br>
<br>
Encoding:
:CHR$(0);
<br>
Function:
:The reception of the command NUL results in bit 8 to be regarded as 0 for all received characters.
The procedure of setting up the CPC with the MP-1/MP-2 modulators is described in the CPC's user manual.[[Category:Peripherals]] [[Category:Printers and printer ports]]
