Can only print labels with admin account.

[akrly]

Hi,

I am setting up Inventree at my company So far so good. I really love the system, but I ran into a problem. We have a QL-820NWbc printer and I can print labels with it just fine with the default "admin" account. However, I get the following error when I try to print with another user:

I tried the following already:

• Set admin and superuser privilege
• Create new users
• Creating labels with the built-in pdf plugin (this was always a success)

I am running a Docker install. Let me know if I need to provide further details.

@akrly interesting.. Can you please provide full version information for your installation?

And the "admin" account is always successful, even when you are trying to print the exact same label items?

[akrly]

Okay so I was just about to send you my reply and thought let's try it one more time. I wanted to double check printing multiple copies of the same stock item .... and now it works. The only thing I did is that logged in and out of accounts.

Just to give more context:

The first time this problem occurred was yesterday. I showing a colleague how to do data entry, scanning and label printing. So I thought he can use the admin account and I'll try to hunt the bug down. After going through config, admin and plugin menus I couldn't find the root cause. That's when I raised the issue.

And here we are now. :) I successfully printed labels with the same printer from the an account that has superuser privileges and also one with only view access.

However, I am still curious what could be behind the error. Could it be a networking issue? The printer is wired to our network and the docker is running on a VM in-house on the same network.

I think that because it is reporting a 404 it is likely that the ID of the item you tried to print did not match a valid item in the database.

Note that in later versions of InvenTree the entire printing framework has been updated and refactored - and I am pretty sure this issue has subsequently been resolved.

Glad you got it working!
