   If you are using AmigaBasic, I just posted an example that works fine
on my printer (MPS-1000).  It uses prt:.  This example is similar.

OPEN "prt:" FOR OUTPUT AS #4
esc$ = CHR$(27)+"["
den2$ = esc$+"2"+chr$(34)+"z"
PRINT#4, den2$;"hello"    'Prints hello in NLQ
CLOSE 4

   I use prt: because LPT1: (used by LPRINT) eats initial sequences.

   If you are using C, then you are either doing something wrong or
your printer doesn't support NLQ.  Make sure you have the correct
printer-specific driver selected in Preferences.  It is the driver
which converts the ISO sequences to printer-specific ones.

   You can test the sequences from CLI.  Try typing the following.
Everything typed between the first and last line will go to prt:.
(Note: <RET> is the return key, <ESC> is the escape key)

copy * to prt:<RET>     
<ESC>[2"zhello<RET>
<ESC>[1"zhello<RET>
CTRL-\                  (Note - Hold CTRL and type \)

   With my MPS-1000, this prints "hello" twice, first in NLQ then normally.
