Printing via printnode (Error 400): Bad Request

[sfd_pl]

I would like to do printing from my Appsheet and found printnode solution from DIY Replacement for Google Cloud Print (Shutting Down Today) - #63 by sfd_pl.

But I’m hit with error 400. See below.

My end goal is to print barcode from my GoDex RT700iW label printer when i fire an instruction.

This will not work if used outside of AppSheet:

<<[Product ID]>> is a template instruction interpreted by AppSheet. Outside of AppSheet, it has no special meaning and will not be handled as AppSheet would. You cannot test the web hook using your testing tool with the template instruction.

Hi Steve,

I followed the @aijac1314 video. Below is the snapshot from his video(7:00)

[aijac1314]

Dear @sfd_pl , have you disable the “Require Image and File URL Signing”?

You can find the setting under Security → Options

[sfd_pl]

Hi aijac1314,

Disabled. Still getting error 400

[aijac1314]

Can you access the link itself by just paste the addess in any browser?

[Steve]

This URL will never work if used outside of AppSheet. Even within AppSheet, the URL is only usable in very select places. Both of you have incorrect expectations.

[sfd_pl]

Ok Steve, will manage my expectation

Have you come across any appsheet that have successful print via printnode??

What im trying to achieve to allow user to print barcode label of the selected item.

label will consist of 2 text field and 1 barcode.

Are you able to access the generated PDF file with the URL?

Can you share your URL?

I do try again with the demo program in the video, it is still working.

[aijac1314]

Make sure the URL is accessible with browser, like this:

Above is accessible file

Above is a non accessible file.

Hi,

Struggling to make this work too, I see this when I try to access the URL from a browser, i.e non-accessible.I have disabled 'require Image and File URL Signing' and also updated the file on google drive to allow unrestricted access. 

Any other ideas to make the file accessible?

Any help gratefully received!

thanks

You may check the URL in BOT → MONITOR, as below:

[Steve]

The same answer given above applies to you as well.

Hi aijac1314,

Sorry for my much delay response over festive season.

My appsheet are not deployed at the moment. Does that have any impact?

My monitor page(Process> Steps> Detail)

My URL - https://www.appsheet.com/template/gettablefileurl?appName=Production-4995105&tableName=Label&fileNam...

I noticed you create a new virtual column for the URL.

Wishing you and family a happy new year ahead!!

This error indicates printnode.com is refusing your connection. You’ll need to get help from printnode.com for that.

[sfd_pl]

Ok will check with printnode on this error
