I’m happy to say I have just released a printer extension for TastyIgniter to the market place. https://tastyigniter.com/marketplace/item/thoughtco-printer It supports USB (ESC/POS), IP/Network Printing (ESC/POS) and printing through the Epson ePOS network web service. You can add multiple printers per location, format the docket per printer, and can limit what is printed to each device by category selection. A huge thanks to those who helped beta test this extension - your feedback was really valuable and I appreciate all your time. If you have any questions about the extension, check through the readme, but if that doesn’t help add your questions here or message me on slack ( https://tastyigniter.slack.com/team/U013ENYFQLR ) and I’ll do my best to help.

Hey, I just paid for the extension. It still doesn’t show up on my admin panel. How does this exactly work ?

raj I’m not sure of the inner workings of the marketplace, but @sampoyigi replied to a similar comment here: https://forum.tastyigniter.com/d/1929-how-the-heck-do-you-install-an-extension/3

The caching issue was fixed in v3.0.4-beta.22 so the item will appear in the admin dashboard after purchase if you are using the latest version.

Wow this is awesome! Will probably buy this in the next few weeks.

I couldn’t do the settings, can you take a video of installation and setup please,

@bima the settings very much depend on your local printer setup, so a video would not be universal. Feel free to reach out to me on Slack and I will guide you as best I can.

Thanks, when I click on the print button, a new page opens. (1/1) ErrorException Array to string conversion in StringParser.php line 59 this error page opens

@bima if you apply the fix in this commit, that should go away: https://github.com/tastyigniter/flame/pull/11/commits/820e7cee3599d9096596397beff8db8843feeeb5

Thanks, the problem has been fixed, but the order total information is missing in the order receipt.

bima as in the info is blank or the variable remains in the print out? Might be easier to reach out on slack and we can debug.

ESC/POS Printing

It depends on the codepage and character set you select in the printer settings. You need to choose a codepage with the characters you want and ensure that matches the character set too

Hello, I want buy this extension for my clients, but will know is necessary pay every years for use? or just one time ?

ryanmitchell

It is an annual fee for updates.

xujiongze

ryanmitchell Ok, so we can pay one time if no update right?

ryanmitchell

Im not totally sure how the marketplace works, but I assume if you pay one time you would only get a years updates.

xujiongze

Am testing with my epson printer, connect with USB port, and replaced driver with zadig, but still can not connect to device.
And when I click “Setup USB Device” happend error JS
Uncaught TypeError: Cannot read property ‘requestDevice’ of undefined
at Object.requestPermission (escprint-1.0.6.js:114)
at HTMLButtonElement.onclick (1:884)

What browser are you using and is your site on SSL?

xujiongze

ryanmitchell Chrome browser, its not on ssl

ryanmitchell

Web usb only works over ssl.

xujiongze

Hello again,
My site work well with usb connection, but now I will connect other printer with ethernet.
Is runned proxy app, configured with local ip and copied certificate from server to proxy app, but when I try to print, show error “Could not connect to printer.”

ryanmitchell

xujiongze You need to generate an SSL certificate for the IP the computer is on, not the one from the server. Please refer to the readme for more information.

xujiongze

ryanmitchell Thanks, I changed my ssl, but still get same error
I test with POSTMAN, can connect my_ip:9001, can send data. I upload PEM file to chrome

JS error : WebSocket connection to ‘wss://127.0.0.1:9001/’ failed:
(anonymous) @ printdocket?sale=1:671
(anonymous) @ printdocket?sale=1:713

ryanmitchell

xujiongze Share your proxy config screen so I can verify the setup

xujiongze

ryanmitchell

This doesnt line up with your error (JS error : WebSocket connection to ‘wss://127.0.0.1:9001/’ failed) - as you are connecting to 192.168.1.36 not 127.0.0.1 …

be sure your SSL cert is for 192.168.1.36, stop and start the proxy again.

In chrome you can go to chrome://flags/#unsafely-treat-insecure-origin-as-secure and set the IP of 192.168.1.36:9001 to be secure even if you dont use the SSL option.

I have to head on here, so wont be able to answer any further questions - others have set this up successfully so should be able to help

xujiongze

ryanmitchell
Thanks, should be my SSL problem, I actived #allow-insecure-localhost and #unsafely-treat-insecure-origin-as-secure, and work!

Last problem, is this support UFT-8 or GBK chinese encoding ? None of the existing encoding options seem to support Chinese

Thanks

ryanmitchell

That depends on your printer really. If you need another option added you can do it manually, or reach out on Discord and I can work to add it to the main printer releases.

xujiongze

ryanmitchell
Am sure my printer can print chinese character with my pos app.
I found have chinese encode “gb18030” in encoding-index.js , and I added “gb18030” to model/Printer.php getEncodingOptions(), but it not work, It prints some garbled characters no Chinese characters.

Is there anything else I need to modify?

ryanmitchell

Not sure, depends on the printer and I havent really tested Chinese characters using the proxy app. You could try just returning $string in removeUnprintableCharacters() in PrinterFunctions - asides from that I would need to purchase the actual printer and test on it to be able to help any further.

xujiongze

ryanmitchell
Still prints same garbled characters, am trying with USB printer not with proxy.
Could it be another problem?
