NLQ401

NLQ401 DIP Switches
Function Off = High = 1 On = Low = 0 Software
DS1-1..8 Reserved DS1 is not installed, DS1-1..7 floating (without pull-up), DS1-8 hardwired to GND (On)
DS2-1 Page length 11 inch (default) 12 inch Can be also changed via ESC "C"
DS2-2 Line Feed Spacing Force ESC "2" to act as 1/8 or 1/6 inch
Note: Service manual claims DS2-2 selects UK/French characters, that is wrong, not supported by firmware
Can be also changed via ESC "A"
DS2-3 International characters Select US-ASCII or German characters Can be changed by ESC "6" / ESC "7" (which are NLQ401-specific codes, non-Epson compatible)
DS2-4 Draft/NLQ Mode Select Draft or NLQ mode
Note: Service manual claims it selects Slashed/Unslashed Zero, that is wrong.
Can be also changed by ESC "x" (Epson-compatible code), or by ESC "I" (equivalent NLQ401-specific, non-Epson compatible code)
DS2-5 1 inch skip perforation Invalid/Disable (default) Valid/Enable Can be also changed via ESC "N"/ESC "O"
DS2-6 Not used Unused according to service manual, that is wrong. It seems to control something like wrapping to next line when the line is full (or so) ?
DS2-7 CR Function CR+LF CR only (default) Affects chr(0Dh) / Also affected by /AUTOLF signal
DS2-8 SLCT IN Exchange External Internally fixed (default) ?
