<ESC> sequence for printer
<ESC> sequence for printer
(OP)
On the EPSON printer "<ESC>G" commands double print
Similarly different <ESC>???? seqences mean different
other commands.
Is there any way to find out the different control codes
for other printers ? Or at least find a character
sequence which would be interpreted by any printer
as "NO-OP" ?

PCL is a bit confusing at first for some things, but once you get the hang of it, the essentials aren't too bad. I had to do this a while back so I could assemble a stream of "RAW" data to a printer under Windows, from a Fortran program. I posted this on the Lahey.com web site under their "Code Repository" if you are interested.

I had that book, but it's been so long since it's been useful that I haven't a clue where it is or what the exact title was.
Barring that, you might just have to hunt through the various manufacturer sites for the printer manuals.

This standard includes many formatting commands, as well as some specific POS related commands like cutting receipts, printing bar codes and opening cash drawers attached to the printer. It is quite standard for POS printers. Many manufacturers support this standard, including many non-POS devices. However, most use a subset, or a superset of the commands.
I cannot remember any no-op command in EscPOS. But unsupported commands are ignored by the printer. That may behave like no-op.
I do have some documents on EscPOS. If you need further info, you can contact me.
