== NLQ401 Control Codes ==
 +
 +
The [[NLQ401]] supports a fraction of the Epson control code set, plus some NLQ401-specific, non-Epson codes. The missing Epson codes include both newer codes, as well as older ones (like vertical TABs, which are supported even by very old Epsons from 1981).
 +
 +
Caution: The NLQ401 firmware strips Bit7 of all incoming characters, so one is restricted to use 7bit codes, even if one does own an [[8bit Printer Ports|8bit Printer Port]]. Accordingly, only 7-pin graphics can be used, and some numeric parameters cannot be set to values with bit7=1.

DMP1 Control Codes

Hex Decimal ASCII Type Description
0A 10 LF Misc CR+LF
0D 13 CR Misc CR or CR+LF (selectable via DIP-switch)
0E 14 SO Width Double Width Mode (also restores 1/6" line feed rate; after graphics printing)
0F 15 SI Width Normal Width Mode (also restores 1/6" line feed rate; after graphics printing)
10 hi lo 16 hi lo DLE "NN" Misc Print Position in character units (NN = two-digit ASCII, "00..79")
14 20 DC4 Misc CR
1B 10 hi lo 27 16 hi lo ESC DLE hi lo Misc Print Position in dot units (hi:lo = 9bit binary, 0..479) (lo=lower 7bit, hi=upper 2bit)
1B 4B hi lo gfx0 gfx1 .. 27 75 hi lo gfx0 gfx1 .. ESC "K" ... Graphics Graphics Mode (hi:lo = 9bit count, 0..479) (lo=lower 7bit, hi=upper 2bit) (followed by as many bytes, with bit0=upper pixel .. bit6=lower pixel). This command additionally changes the line feed rate to 1/9 inch; the new rate is kept applied for text and graphics (until canceled by chr 0Eh/0Fh).
1C num gfx 28 num gfx FD,num,gfx Graphics Repetition of one byte of graphic print data (num=1..127 repeat count) (gfx: bit0=upper pixel .. bit6=lower pixel)

NLQ401 Control Codes

The NLQ401 supports a fraction of the Epson control code set, plus some NLQ401-specific, non-Epson codes. The missing Epson codes include both newer codes, as well as older ones (like vertical TABs, which are supported even by very old Epsons from 1981).

Caution: The NLQ401 firmware strips Bit7 of all incoming characters, so one is restricted to use 7bit codes, even if one does own an 8bit Printer Port. Accordingly, only 7-pin graphics can be used, and some numeric parameters cannot be set to values with bit7=1.

Hex Decimal ASCII Type Description
09 9 HT Tab Horizontal tab
0A 10 LF Feed Line Feed (move to next line)
0B 11 VT Feed NLQ401-specific: acts as mirror of LF (non-Epson code)

1B 57 n 27 87 n ESC "W" n Text Style Double width mode ON/OFF (continous) (unlike DC4: one line) (00h=off, 01h=on)

1B 62 c .. 00 27 98 c .. 0 ESC "b" c .. NUL Tab Define up to 16 vertical tabs per channel (c=0..7) with ascending values from 1..255; specifying an empty list (ESC "b" c NUL) clears that vertical tab channel; channels are selected via ESC "/" and can be then used with chr(09h); there is also a similar command without channel-numbers (ESC "B")
1B 69 n 27 105 n ESC "i" n Misc Instant character printing (00h=Off=default, ie. print only on LF, 01h=On=print each char immediately; also scrolls printed text into view; when buffer empty) (not on LX80)

1B 73 n 27 115 n ESC "s" n Misc Half speed mode (00h=Off=Normal, 01h=On=Slow; purpose: noise-reduced silent printing)
1B 78 n 27 120 n ESC "x" n Text Style Select Draft/NLQ mode (00h=Draft, 01h=NLQ) (LX80) (FX86e) (not FX80)
7F 127 DEL Misc Delete last character from buffer (but not control codes) (works only when buffer isn't yet printed; printing usually starts on terminating lines via LF)
  • Character codes 00h-FFh...
    • Codes 00h..1Fh and 7Fh contain control codes, but at least some of them can be also used as print-able characters; at least when enabled via ESC "I1" (according DMP2000 manual chap6/page7 example: chr(6) is a print-able (user defined) character. others like chr(27) are obviously not printable)
    • Codes 20h..7Eh are ASCII characters (some changed in "international" modes)
    • Codes 80h..9Fh and FFh act as mirror of control codes 00h..1Fh and 7Fh (this mirroring can be disabled via ESC "6")
    • Codes A0h..FEh are italic versions of 20h..7Eh
  • The DMP2000 (and up) supports all Epson FX80 control codes, plus some additional ones:
    • ESC SO and ESC SI (mirrors of SO and SI) (for some reason, these mirrors are often supported by Epson-clones like Star LC10, though they are rarely found in official Epson specs)
    • ESC "x" n (select NLQ/Draft mode) (the original Epson FX80 didn't support NLQ, however, the ESC x command is found in other Epson models like LX80 and FX86e)
    • ESC "m" n (select IBM charset) (this seems the be an Amstrad invention, supported only by DMP3000/3160, not supported by DMP2000/2160, nor by real Epson printers, nor by Epson-clones like Star LC10).
  • Some one-digit parameters (like on/off flags) may be recognized both is binary chr(0xh) as well as ASCII chr(3xh).
