hpiscnapp.exe command line switches

[Pivyslayer]

Now that the Solution Center no longer works, the scan app, hpiscnapp.exe, remains and is usable.   When I try to use it, Unfortunately it defaults to Images.  I appears the Solution Center was just a skin to call this (and other) executable(s), so what switches did the solution center use to start hpiscnapp.exe for Documents/PDF files?

Hi,

Please try using HP Scan Extended as listed below, I believe it might better fit your needs:

I have already been to the link you suggested.   I tried to go to find and download "HP Scan Extended" on that web page and it displayed an empty web page and just sat there (link must be broken), so that is no option.  The "dodge my question" solution, HP Scan and Capture, has no ability to alter the quality of the PDF image (only rotate).  That is why I was looking for a way to call the old executables with command line switches because they had more capability.  Obviously it can be done since I can use  the old hpiscnapp.exe directly for images, I just want it to give me the documents option.

Please try downloading it using below link and let me know if you may see any difference then:

Once completing the installation, open the HP Scan Extended Software and try scanning, it have many capabilities and feature, most likely not less than the original software

@Pivyslayer - I was also trying to use hpiscnapp.exe to bypass HP Solution Center problem in Windows 10 with discontinued Flash Player, and I encountered the same pitfalls as you. Then I looked into an older Windows 7 system where Solution Center still works ok, and I discovered that you should call hpqkygrp.exe instead. My printer is an HP Officejet 4500 G510n-z, and I can now scan in Windows 10, using the profiles I had created before the Flash discontinuation, by calling:

hpqkygrp.exe -n"#Hewlett-Packard#HP Officejet 4500 G510n-z#1598391139" -a"SCAN" -f"SCAN_DOCUMENT"

for documents, and:

hpqkygrp.exe -n"#Hewlett-Packard#HP Officejet 4500 G510n-z#1598391139" -a"SCAN" -f"SCAN_PICTURE"

for images.

I can select one of the existing profiles (which tell dpi, color/gray/bw, etc.)  in the window that open on execution. I have not tried yet to create new profiles.

I found the command syntax, the printer-name and 10-digit number passed as parameter -n somewhere in the file:

C:\Users\%USERNAME%\AppData\Roaming\HP\ScLogs\SolutionCenter.htm

Note that the 10-digit number was different between my two Windows installations (Win7, Win 10) even when both use the same printer, so yours will be another number (as will be different the printer name).

I have 'automated' the calling by putting the command lines into two batch files (I'm from the old MS-DOS school).

Hope this helps you.

UPDATE: Thanks to user Wstack, now I know that the data for parameter -n comes from the Windows Registry entry:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Print\Printers\{Your Printer Name}\PrinterDriverData\SoftwareCUEContextID
