HPScan.exe, HP ENVY 4500 series.exe, v.s. #hId-pgWebScan

[hmazuji]

hp scan and hp print assistant scan produce horrible image quality when scanning a b&w photo to either jpeg or pdf

however, using the web interface, scan tab, saving the resulting image works great

just curious if anyone else has this issue or experience, and if there's a solution for the software, besides using a web browser, although the web browser workaround is first rate

Welcome to the HP Support Community.

Change the scan settings with HP Printer Assistant.

1. Load the item on the scanner glass, in the document feeder slot, or in the automatic document feeder (ADF), depending on your printer type and features.

   NOTE: 

   Do not load photos in the ADF to prevent damage to the photos and the printer.

2. Search Windows for your printer model, then click the printer name in the list of results.

   HP Printer Assistant opens.

3. Click Scan, then click Scan a Document or Photo.

   HP Scan opens.

4. Click one of the shortcuts that matches the file type and resulting action you want.

5. Change any of the shortcut default settings in the right side of the window, if necessary.

   NOTE: 

   Available settings change depending on if you are scanning a document or photo. For example, the PDF File type is only available for document scans.

6. Select Show scan preview or Show Viewer After Scan to preview and make additional edits to the scan before saving it.

7. Click Advanced Settings or More to change settings such as quality, color, and default scan destination folder.

8. Click Scan.

   The printer scans the item, then a preview of the scan displays in HP Scan.

9. If necessary, double-click the thumbnail image of the scanned item, then change any additional settings.

10. Click Save.

    The Save as windows opens.

11. Select the folder you want to save the scan to, change the File name if necessary, confirm the file type in the Save as type menu, then click Save.

If the issue persists, let's do a root uninstall and reinstall of the software:

Unplug any USB cable, if any, before doing this.

1.) In Windows, search for and open Programs and features

2.) Select your HP Printer

3.) Select Uninstall

4.) In Windows, search for and open Devices and printers

5.) In the Devices and Printers windows look for your HP printer. If you see it listed right-click on it and choose 'Delete' or 'Remove Device'

6.) Open up the run command with the "Windows key + R" key combo.

7.) Type printui.exe /s and click Ok. (Note: there is a space in between “printui.exe” and “/s”)

8.) Click on the "Drivers" tab

9.) Look for HP Printer driver. If you see it Click on it and click Remove at the bottom

10.) Select Ok

11.) Select Apply and Ok on the Print Server Properties windows

12.) Close Devices and Printers

13.)  Open up the run command with the "Windows key + R" key combo.

14.) Type c:/programdata and click Ok. Go to Hewlett Packard folder, remove any printer related folders & files.

15.) Restart the computer.

Once done, please download and install the software from here:
