Hi Razmans, when I create a new Buffer, I have to input 2 values as the arguments, size and block size. Would you be kind enough to tell me what those values mean as I couldn’t find much of it on google. What size would you recommend the buffer to be? Also when I specify this.buff.write(CMD.Text_FORMAT.TXT_ALIGN_CT); // Cannot find the name CMD…Is there anything I need to import? Can I use the hexadecimal value ‘\x1b\x61\x01’ as the argument of the write() method instead?
Thanks!
Sir can you help me. I can’t use your code. The CMD keyword not supports coding. What did you do to make it work? do I need to install package?
Sorry for the late response, I use version 2.0.3 mutable buffer, its very straight forward and you dont need to define block size.
Take note of the data object that I have created in the markdowns:

I’ve declared the above markdowns elsewhere first and i call CMD such as below:
let CMD=data;
that’s how i am using CMD. Hope that helps
Thank you! It works likea charm! God bless you!
hi ,i follow your sample and every thing is fine but i have a problem in arabic font how i could write arabic data
thanks for your help
this works but is there anyway we can print html formatted receipt on thermal mobile printers?
Sir !
Thanks very much, I can print English and numbers,
but can’t print Chinese word…, such as “謝謝”,
how to fix it ?
Thanks a lot
hi @razmans , i have followed the tutorial that you gave and succeeded, but how to combine text and barcode print? please help me.
Sorry for the late reply. Barcode print is on my to do list.
please give me your code example, I really need it with barcode print and text
Is there any chance to get something like this with codes above ( alignment ):
Name: John
Age: 24
City: Berlin
Gender: Male
I need 2 alignments in one row, like example above, ‘Name’ should be aligned left and ‘John’ should be aligned right, but both in same row?
\x1b\x61\x00 Name: \x1b\x61\x00 \x1b\x61\x02 John \x1b\x61\x02
\x1b\x61\x00 Age: \x1b\x61\x00 \x1b\x61\x02 24 \x1b\x61\x02
\x1b\x61\x00 City: \x1b\x61\x00 \x1b\x61\x02 Berlin \x1b\x61\x02
\x1b\x61\x00 Gender: \x1b\x61\x00 \x1b\x61\x02 Male \x1b\x61\x02
See below for my response
Im using it as buffer like this:
Try 1:
this.buff.write(CMD.TEXT_FORMAT.TXT_ALIGN_LT)
this.buff.write('Name: ‘)
this.buff.write(CMD.TEXT_FORMAT.TXT_ALIGN_LT)
this.buff.write(CMD.TEXT_FORMAT.TXT_ALIGN_RT)
this.buff.write(‘John’)
this.buff.write(CMD.TEXT_FORMAT.TXT_ALIGN_RT)
Try 2:
this.buff.write(CMD.TEXT_FORMAT.TXT_ALIGN_LT + ‘Name: ’ + CMD.TEXT_FORMAT.TXT_ALIGN_LT + CMD.TEXT_FORMAT.TXT_ALIGN_RT + ‘John’ + CMD.TEXT_FORMAT.TXT_ALIGN_RT)
Try 3:
this.buff.write(’\x1b\x61\x00’ + ‘Name:’ + ‘\x1b\x61\x00’ + ‘\x1b\x61\x02’ + ‘John’ + ‘\x1b\x61\x02’)
None is working. Actually it aligns all text to the right.
Thx for useful answer, i have one more question i need to change codepage for my bluetooth printer, so i it properly prints chars with cyech diacritics. Iam testing it on this printer : https://www.e-birch.com/buy/main_products.php?pid=1408&mt=1
But it prints chinese chars instead of czech ones
// //barra
// receipt += ‘\x1d\x77\x04’;
// receipt += ‘\x1d\x6b\x02’;
// receipt += ‘111114123457\x00’;
hey @razmans i follwed your steps but my bluetooth printer is not support the POS commands how to find supported commands.
Hey @razmans, I can print plain text, but could you show me an example to print bar codes, using BARCODE_FORMAT… Please (y)
