Exchange data with local fiscal printer

I may have a problem with the new Firefox version 152: from my online application, I send a command string to a local printer reachable at https://192.168.1.xxx. It often succeeds, but sometimes it gets blocked. I don't understand what the problem might be because I don't get any error messages. The only thing I see that's different from the usual is this:

Local network access detected: main site "https://www1.storesales.it/alpha/RTL/veve.php", initiator "https://www1.storesales.it/alpha/RTL/veve_chiudi.php", accessing destination "https://192.168.1.xxx/cgi-bin/fpmate.cgi" (192.168.1.xxx:yyy) via xhr. Safe context: True, action prompt: (null)

However, it looks like an informational message saying everything is OK.

It seems that Firefox sometimes waits before sending the XHR call, which causes the call to time out. I have no evidence to confirm this. I don't know where to look for evidence. What can I do?
