# Error Message: 'Wrong Parameters Specified'

When printing a Lasernet report to **Lasernet Screen** or using **Review before sending**, the following error occurs if no records exist in the **DocuType** table:

## Solution

To solve this issue, navigate to **Organisation administration** > **Document management** > **Document types**.

When opening the **Document types** form, the following four records are automatically created if the **DocuType** table is empty:

If you wish to print to **Lasernet Screen**, **File** must be the first record in the **DocuType** table. **File** does not need to be selected in the **Document type for preview** field in **Lasernet parameters** form. If this parameter is not specified, Lasernet FO Connector will use the first record from the **Document type** form.

**Document type for preview** must be specified only if the first record in the **Document type** form is not **File**, and if its **Location** is not **Azure storage**.
