Amstrad/Schneider Printer Support for 7bit Printer Ports

/* Schneider NLQ401 */
== Schneider NLQ401 ==
The [[NLQ401]] uses a raw 7bit 7 bit protocol so all functions are working with 7bit 7 bit ports. Actually the printer does have an 8bit 8 bit port, and does use standard Epson codes (which can include 8bit 8 bit parameters), but the printer firmware strips the MSB immediately after reading data from the centronics port - so one is stuck with 7bit 7 bit codes, even if one owns a computer with 8bit 8 bit printer port.
Restrictions on 8-pin graphics and numeric parameters are same as on DMP2000 (see there for details). Restrictions for 9-pin graphics and user defined chars don't apply (since the NLQ401 doesn't support these features).
