KeyError: 'finishing roll printing'

This error occurs when you try to access a dictionary key that does not exist. In this case, it seems like you are trying to access the key 'finishing roll printing' from a dictionary, but this key does not exist in the dictionary.

To fix this error, you need to check if the key exists in the dictionary before accessing it. You can do this using the `in` operator or the `get()` method.

For example, if your dictionary is `my_dict`, you can check if the key exists using:

if 'finishing roll printing' in my_dict:
    # Access the value here
else:
    # Handle the case where the key does not exist

Alternatively, you can use the `get()` method to access the value if the key exists, and provide a default value if it does not:

value = my_dict.get('finishing roll printing', 'default_value')

This will assign the value corresponding to the key 'finishing roll printing' to `value`, or assign the default value 'default_value' if the key does not exist.
