This application provides a way for a user to send a predefined PDF to a predefined printer, using OTP (One-Time Password) generation and verification. One use of this application is to send a predefined signature to a printer, allowing the user to effectively "sign checks" by printing the signature over the top of printed checks.

It is built using Flask and includes logging for important events.

• Python 3.11+
• pip (Python package installer)
• Virtual environment (optional but recommended)
• PDF to Printer (or any other PDF to Printer software)

1. Clone the repository:

   git clone https://github.com/jcarter62/doc-signer.git
   cd <repository-directory>

2. Create and activate a virtual environment (optional but recommended):

   python -m venv venv
   source venv/bin/activate  # On Windows use `venv\Scripts\activate`

3. Install the required packages:

   pip install -r requirements.txt

4. Set up environment variables:

   Create a .env file in the root directory of the project and add the following variables:

   PRINTER_EXE=c:\...\PDFtoPrinter.exe
   PRINTER1=hpprinter
   NAME=Jim User
   EMAIL=[email protected]
   PDFFILE=c:\temp\one-page.pdf
   OTP_FILE=c:\temp\otp.txt
   EMAIL_SERVER=192.168.1.100
   EMAIL_PORT=25
   EMAIL_FROM=[email protected]
   HOST=0.0.0.0
   PORT=5000

1. Static Files:

   Ensure that the image files are placed in the static directory. For example, pen-writing-on-check.png should be located at static/pen-writing-on-check.png.

2. Templates:

   The HTML templates are located in the templates directory. You can customize home.html and success.html as needed.

1. Start the application using run.py:

   python run.py

   This will start the server with logging configured in run.py.

Logging is configured in run.py to log important events and errors to the console. You can view the logs in the terminal where you start the application.

1. Generate OTP:

   Navigate to the home page and click on "Generate New OTP Code". The OTP will be sent to your email.

2. Verify OTP:

   Enter the OTP code received in your email and click "Verify OTP Code".

3. Print Signature:

   After OTP verification, enter the quantity of signatures to print and click "Print".
