How to install python3-pyqt4 on Linux Mint 20? HPLIP dependency

In order to install HPLIP 3.20.6 I need to install the dependency python3-pyqt4. > error: A required dependency 'python3-pyqt4 (PyQt 4- Qt interface for Python (for Qt version 4.x))' is still missing. > error: Installation cannot continue without this dependency. > error: Please manually install this dependency and re-run this installer. When trying to install through apt I get the error that it cannot be found. > E: Unable to locate package python3-pyqt4 How can I install this dependency? I need to install HPLIP 3.20.5 or greater in order to be able to use a new printer so any help in resolving this is much appreciated. Thank you. Edit: To further clarify. The printer I am trying to connect to is HP Envy 6020. On the HPLIP list of supported devices the Envy 6000 series is supported but it requires a minimum of 3.20.5 HPLIP to run. Ergo, I need to install that version and it is requiring python3-pyqt4 in order to install.
