Yes, my printer is responding to ESC/P commands like cut paper and line
feed.
If I use a API function called "Escape", I print text fastly, but I
can't print bitmaps.
My printer is a Samsug SRP-350 and, according their manual, the
commands to define and print images are, respectively, "<FS> q n m ..."
and "<FS p n>", but I don't found any kind of information about that,
so I'm trying to use standard ESC/P commands to do it.
If nobody know how can I do it, there aren't any problem, because I
solved using Printer.Canvas object.
Thank you very much

Sorry to put it this way, but even un-professional end users that have
some printing problems usually are able to tell what printer model tehy
are using. Yet you decided to keep your secrecy about the SRP-350 model
this far...
I have no idea what you are actually trying to do with your Delphi and
with those ESC-sequences to print bitmap graphics etc. I earlier already
made my suggestion to use standard Windows printing tools, and I will
not repeat that all again.
I'll only tell this:
-Theres's standard Windows driver available for SRP350 printer, offering
all the usual Windows graphics printing capabilities.
-If you have speed problems in graphics printing, select USB or LPT
interface instead of serial interface. You can easily change the
interface card in SRP-printer, the cost is about 5$..6$.
-To send the needed ESC-sequence for SRP's paper cutter, the current
SRP-350 drivers will do it all for you.

You can set what sequences the driver sends to the printer before and
after the data you sent to the printer.

That is the old and hard way, and someone probably is able to tell you
how you can also go trough that path.

I've done a hunt and found a PDF manual for the SRP-350
It is at:
http://www.goodson.com.au/support/Download_UM_samsung.htm
It contains a full table of 'ESC' codes
From looking at the file, it appears that the printer uses a hybrid
set of control commands - a bit different from ESC/P
<FS> p n m 1C 70 n m Print NT bit image
Looks like <FS> is used instead of <ESC> here,
- Chr(2 instead of Chr(26)
There are also some interesting commands for storing and printing a
stored bitmap
The printer also supports a 'Star emulation mode' that looks like an
old version of Epson - probably wise to avoid that - initially at
least.

For curiousity I would be inclined to get the printer working using
all possible modes and give it a software configuration so you can
switch modes.
If nothing else it will ensure that your print routine is generic
which will be handy /when/ (not if) the client decides to use another
printer.
The way I do it is to embed human readable 'control characters' in the
docket, then pass that text through an interpreter that converts the
'human readable' codes into the real 'ESC' codes, that way one can
print to screen in debug mode which is distinctly handy.
I would also be inclined to run up a little testbed App for
demonstrating and testing the various print commands.
