# Scan2Folder

## Enabling the Scan-to-Folder button on HP MFP printers

This is a **PytQt6** desktop app for rapidly scanning documents by using the Scan-to-Folder button on HP Multi Function Printers (MFP)
especially CM Devices.

This app uses the **Sane** backend to get all parameters needed.

It also provides image enhancement features.

>*Note: in this version only the first scanner is used*

**NEW:**    Config profiles
> If you want scan document with different page sizes it may usefull to save each configuration into a seperate profile

OCR processing and PDF-Document creation or from local images.
> The *Scan2Folder*-Button has a new function.  
> By pressing the button it opens a file dialog where you can select your image files  
> you want to procees.  
> *Note:* the filenames must be numbered like this `<filename>_[1..n].png`

OCR processing and PDF-Document creation from your scanns.

After you finished scanning, you can start an OCR-Process
The OCR-Process will do the following steps:

1. Deskew each page
2. Crop the image
3. Check text orientation
4. Start ocr
5. Create searchable PDF

You can define the crop size in the configuration dialog

>*Note: In this version A4 page size for 300dpi is predifned.*
If you want to change this, you can do it in ocrtools.py

### Usage

1. Ensure that your scanner is reachable
2. Start the app
3. Select a *ScanMode*
4. Select a path where you want to store your images
5. Enter an image prefix name. All the scanned images will enumerated automatically.
6. Choose a scan resolution
7. Press the *Start Service* button

If the scanner is reachable the LED turns on green and you can use the scan-to-folder button on your device.

### Image enhancement

On clicking the `Config/Calibrate` menu opens a window where you can scan a preview image.

>*Note: the scan button is only enabled when the service is running.*

>*Only flatbed scanning is supported*


### Installation

Install packages needed with:

>`sudo pip3 install -r deps/dependency.txt`

#### For OCR

Install tesseract-ocr 4 with your language **and**  with Orientation & Script detection


### Features

* creates PDF from local images
* spec file for creating stand alone binaries
* Image name is cleared when stopped a scan session
* Image name has now auto complete, to avoid overwrite existing files

### Issues

* The script is tested only with a HP CM1312 device
* Only one (the first) scanner is usable
* If the LED does not turn green after the device is switched on, may be your device is not supported
* If the LED does not turn green and the button keeps yellow, the scanner is locked by another device/thread
