Looking at my old scripts, I see stuff like this for setting up the
receipt printer:
get printSend(numToChar(27) & "@") -- reset
get printSend(numToChar(27) & "1") -- 8 dot line spacing
get printSend(numToChar(27) & numToChar(32) & numToChar(1))
where the printSend function did the actual communications to the printer.
So in your case, I would try sending:
numToChar(27) & "d0"
and seeing if this works.
If it doesn't, then try these:
numToChar(27) & "d" & "0"
numToChar(27) & "d" & numToChar(32) & "0"
If it still doesn't work, try
numToChar(27) & numToChar(100) & numToChar(48)
One other thing to check is if the command needs to be ended with a
line feed and if so, which one. The usual options are numToChar(10),
numToChar(13) and CRLF.
You have 2 commands: ESC d 0 and ESC d 1
Do these need to be sent in sequence? Maybe one moves the cutter
across and the other brings it back.
If so, you may need to experiment with timing to work out how long to
leave between commands.
But as far as the communications go, if you can work out the technique
for any command, you can apply that to all the printer features.
Cheers,
Sarah
