In case you still get the HP error message 49.4 c02, you can call the HP printer customer support team for the right assistance and professional help. However, you can easily fix this issue just by deleting the error-causing queue jobs.

Now, you must be wondering what causes this error! Well! The printing tasks that are in the queue are the biggest cause behind this error. This HP printer error 49.4 c02 typically disturbs all the printing and related tasks. Even the order and stability of the tiles and interface keep changing and the app freezing or stuttering, as if the app couldn't get any worse.HP Error 49.4 c02 is one of the most common bugs that all HP users must have come across at least once in their lifetime while using the printers. The other 'tiles' in the app are full of self-promotion and wheeling and dealing to make you buy more HP products or services. Since I mainly use my phone, and am forced to use the HP Smart app, which is rudimentary at best and full of issues like the forementioned login issue, it's about what you expect from a low quality printer app. The lowest, trashiest version of an app will exist here, and that's saying a lot for an already pathetic app like the HP SMART app. The second, much worse, buggy version, the one I've been fighting with, is the Android version. Here's the hierarchy of apps in general, for those who haven't figured it out yet.

HOWEVER, this is only an issue if you cannot manually input your SSID and password, which is the case for the utterly worthless HP SMART app, which is anything but SMART. Even though the guide looks nothing like the app and the app has none of these menus or features. I absolutely hate when online guides made by some manufaturer tell you about obsolete or removed functionality in their app. This function literally does not exist in the app. This was my biggest headache before the HP login issues started rearing it's ugly head. People asking questions about setting up or changing WIFI with canned responses from HP forums. When it tells you that it needs bluetooth and location even though the app doesn't ask for these permissions in the phone, because it is lazily written as a one size fits all design that doesn't care what model you have. Searching for the printer in the app, it spins for a few seconds. Not only is their software abyssmal, but the biggest, most egregious design is that it REQUIRES AN INTERNET CONNECTION AND HP ACCOUNT TO USE THE SCANNER, AND THEIR SERVERS ARE ATROCIOUS AND DON'T CONNECT HALF THE TIME.
