    "hp-laserjet_cp1520_series-ps.ppd" looks just right to me.
    
    Did you compared current firmware version of your printer with the
    available firmware update on HP support site?
https://support.hp.com/us-en/drivers/selfservice/hp-laserjet-pro-cp1525-color-printer-series/4052975/model/4052979
    
    In general it's a good idea to keep firmware up-to-date and it might
    fix your issue.
    The only difficulty you might face is the firmware update is
    available for Windows OS only.
    If you don't have any Windows PCs you can create KVM/QEMU virtual
    machine, install evaluation version of Windows 10 on it and redirect
    printer to VM by using USB Host Device function.
    I've updated firmware of another make\model printer using this
    method without any issues.
