Printer Extension - SSL/Websockets Issue

everdaniel

Hi everyone,

so I ran into an issue with the Printer Extension, the first time I set it up it worked fine as the site I was working didn’t had a SSL installed, now that we need to process credit cards with Authorize.net, a SSL is required so I installed it on the site but the Printer Extension stopped working:

The IP address of the computer where the “AutoPrint” page is opened and the Proxy App is running is 192.168.1.179 and the IP address of the printer is 192.168.1.182:

The Proxy App has the SSL cert and private key updated:

And the extension settings were updated to turn on the SSL option:

The SSL and key was created using the following command:

openssl req -x509 -days 1825 -out ssd-printer-192-168-1-179.crt -keyout ssd-printer-192-168-1-179.key -newkey rsa:2048 -nodes -sha256 -subj '/CN=192.168.1.179' -extensions EXT -config <( printf "[dn]\nCN=192.168.1.179\n[req]\ndistinguished_name = dn\n[EXT]\nsubjectAltName=DNS:192.168.1.179\nkeyUsage=digitalSignature\nextendedKeyUsage=serverAuth")

based on the instructions defined on this page, the only thing I changed was localhost for the IP address 192.168.1.179 of the computer where the Proxy App is running:

The certificate was added to the computer as well:

Did anyone ran into a similar issue before? I have no idea what I’m doing wrong and I think I followed all steps as outlined in the docs?

Forgot to mention that I verified that the IP address of the printer is OK as well:

What Javascript error do you get at when you try to print?

ryanmitchell

Also did you stop and start the proxy app again after you added the SSL cert?

everdaniel

@ryanmitchell thanks for your response, the JS error I’m getting is this:

and yes, I first tried to stop/start and after that, closed the app and re-open. I also close/open the browser as well.

Could do with seeing the full detail of the errors rather than just the headline message

sure thing @ryanmitchell – see below:

ryanmitchell

Hmm not much detail there. Not very helpful.

anything in the print proxy logs?

ryanmitchell this is the proxy log:

Also if you have a tm30 is there a reason for not using the epson web service connection method?

everdaniel

ryanmitchell I’m not familiar with that to be honest

ryanmitchell

It’s one of the connection methods the printer extension provides. Means you won’t need the proxy app. I would suggest trying it

everdaniel

ryanmitchell when I select the “Epson ePOS Webservice” it still asks for a IP address and Port, where do I get this info?

ryanmitchell

Check the readme.

for anyone landing here in the future, in the end I had to use Epson’s “ePOS Webservice” to make this work, it just won’t work with the IP/Proxy App combination.

One important thing to keep in mind is that when using this option, make sure that under the Printer > Auto Print tab, the “Set status after auto printing” is set to a status other than the one set under “Auto print order with status”, mine was set to “Leave unchanged” and the end result was this:

My guess is that since the order status didn’t change and it was still “Received”, it kept printing the receipt.
