Hello QZ Print Supportter.
I am a web designer and developer from UK and have been developing Food Delivery & Ordering web application for the last 6 months with Node + React.
Now, I want to add function what store owner can print order information on his endpoint when click Print Button with QZ print.
Please let me know how I can implement that function.
Looking forward to hearing back from you soon.
Regards.

Daniel:
Thanks for your interest in QZ-Tray!
Here is a simple example for implementing QZ-Tray's print functionality:
We encourage implementation with 2.1 at this time.

Thanks for your reply.
I tested print with ESCPOS raw print method to my StarPrinter with follow codes.
But that returns error , and I failed too many times to raw print function for my webstie order for several cases.
Please help me to implement my text order.
var data = [
{
type: 'raw',
options: { language: 'ESCPOS', dotDensity: 'double', },
},
'\x1B' + '\x40', // init
'\x1B' + '\x61' + '\x31', // center align
'Beverly Hills, CA 90210' + '\x0A',
'\x0A', // line break
'\x0A', // line break
'\x0A', // line break
'May 18, 2016 10:30 AM' + '\x0A',
'\x0A', // line break
'\x0A', // line break
'\x0A',
'Transaction # 123456 Register: 3' + '\x0A',
'\x0A',
'\x0A',
'\x0A',
'\x1B' + '\x61' + '\x30', // left align
'Baklava (Qty 4) 9.00' + '\x1B' + '\x74' + '\x13' + '\xAA', //print special char symbol after numeric

Daniel:
Please give a more detailed explanation of the error or provide logs from QZ-Tray.
There are many things that could cause ESC/POS not to print correctly, and I don't want to make any assumptions.
Sharing your operating system and printer model will also be helpful.
Cheers,
Lite

Actually, I want to implement function that print dynamic information order to the customer's raw printer. that don't includes image and include some difference font size and font-weight. Can you explain me what is the best way and code sample for that within today ?
That will help me greatly, I have to complete that function within today.
Thanks in advance.

Daniel,
This public mailing list is offered as a courtesy. If you have immediate support needs, we offer that at buy.qz.io.
In regards to your issue about fonts, Lite's documented a bunch of ESC/POS commands including the text size here: https://qz.io/wiki/2.1-Raw-Printing#escpos
Alternatively you can try to use something like our HTML or PDF processor via our "Pixel" examples.

Daniel:
What is the printer model? This is important because:
1. The Star TSP100/143 cannot process ESC/POS commands on MacOS, for example. It will only work in Windows with the Star driver.
2. The Star TSP654 (and many other Star thermal receipt printers) has a dip switch on the bottom of the printer to switch between "Star Line Mode" and ESC/POS. If the switch is set to the wrong side, it will not print all ESC/POS commands.
ESC/POS fonts are explained in the ESC/POS programming guide. Our code snippets are offered as a courtesy.
Also, please share code, not screenshots. :) If you can show us the code you're using to find the printer and send the data we can identify errors and make recommendations.
Regards,
Lite Finocchiaro

H, How are you?
I am integrating the qz printer into my e-commerce ordering system.
But I have some issues and questions of printing the context with styling... like border, font size, etc...
As the printing content will be changed dynamically according to the order, we can't make a static html, or pdf file.
Now, I am able to print the normal order contents using Raw Printing Generic.
https://qz.io/wiki/2.1-raw-printing#generic
But I can't make some texts to bold and bigger size.
My printer is "Star TSP143IIIU"
https://www.thebarcodewarehouse.co.uk/shop/star/receipt-printers/39472390/Please let me know how to make the styles of texts.
Thanks.
