Ada: Some printer command descriptions

I am doing inventory and want to print labels. I found this thermoprinter in a pile of cables that I want to use for printing inventory labels.

==Hardware==
My printer talks TTL that you can plug into the UART of a Raspberry Pi.

I connected my printer's RX to a Raspberry Pi's TX and both printer and Pi to some power.

There is a large amount of 57mm thermopaper available. You can even buy adhesive thermopaper which is ideal for this project.

==Software==
After plugging in the Printer, you can communicate with it over a serial port. In my case (a Fedora Server 38) this is <code>/dev/ttyS0</code>. You need to set the baud rate correctly for the printer to be able to understand your commands. My printer is at 19200 baud and assuming that your user is in the <code>dialout</code> group this can then be done with
stty -F /dev/ttyS0 19200
This printer speaks ESC/POS. ESC/POS is a printer description language extending ESC/P for point of sale (POS) devices. The printer's spec sheet comes with an explanation of the commands it understands, but it is poorly translated from Chinese, rendering some sections unintelligible. A description of the standard is available from [https://reference.epson-biz.com/modules/ref_escpos_dm_d_en/index.php Epson] which can be helpful for understanding some less obvious commands.

=== Hello world ===
Principally, the printer accepts CP437 characters so you can generally just start printing with regular ASCII by piping strings into the serial port:
printf "Hello world!\n" | tee /dev/ttyS0
This makes the printer print out <code>Hello world!</code> and advance the paper by one line. If however you want to do something more fancy you will need to use some extra commands.

Most commands are prefixed with the ASCII Escape character 0x1b, <code>\x1b</code> in printf, and ''ESC'' for the purpose of this document.

=== Formatting ===
Most commands are documented as something like ESC 3 n. This means an Escape character, the character 3 and an argument. ESC 3 sets the line-height in pixels so the sequence ESC "3" 24 will set it to 24 pixels. It just so happens that my printer's characters are 24 pixels high. If I now want to set the line-height to 24 I can give this to the printer:
printf "\x1b3\x18" | tee /dev/ttyS0
Note that I used <code>\x18</code> to get the character with decimal value 24 (hex 0x18). All lines printed after this will have line-height 24. To show a better example of this, we can print a couple of block characters (0xDB in CP437) and spaces over some lines:
printf "\x1b3\x18\xdb \xdb \xdb \xdb \xdb\n \xdb \xdb \xdb \xdb\n" | tee /dev/ttyS0

The idea of this [[InfoBoxes|InfoBox]] is to display user information in an organized way. It may remind you of the printouts on our [[Members Wall]] - if not, you should probably head over there and print one for yourself ;-)

Feel free to add some information about yourself and just leave out any entry you don't want to show.

== Documentation ==
To use this template, simply copy this code into your page, add the values, or delete lines you don't want to fill out.

Some lines are "smart", i.e. you only have to enter your Twitter username and a link is created automatically. As always, make good use of the "Show preview" function to make sure it works as you expected.
