Problems with blocked PDF documents on websites

Niklars
Hi!
I hope this the the correct sub for this question and I'm new here.
I work as local IT-support and we have a Sophos ASG320 with UTM 9.2 as our firewall. The firewall is configured by our owners with a rather strict proxy policy.

We have a problem which I cant identify. One of our users is trying to print package labels from a website, but the firewall somehow blocks the documents from showing up on the website (works fine outside our network on same computer), and I cant find any thing that is blocked in the firewall log or web filter log. Am I looking at the wrong logs can anyone help me with this?

    Hi there,

    I had a similar Problem with an application that sends emails to a Printer. I've also not seen any log entry.

    The Problem was the transparent smtp proxy. After I've disabled the transparent smtp scanning, the Problem is gone.

    May be, this Web application also sends prints as Email to a Printer.

    Regards

    Documents are not sent to printer directly. A new page with PDF is supposed to open. Works outside firewall.
    Here is the the part from the Live Log.
    I have tried with both IE 11 and Firefox 31.
