Unsolved Powershell (or CMD) to print PDF files
-
Use mailbox message passing instead.
Basically you make a powershell script that runs in a loop. It looks in a folder for file_to_print. When it finds it it send it to the printer, perhaps generate a response.txt file and then the deletes file_to_print.
Your webserver prints by sending the file_to_print into the right folder using ssh (or smb). Then waits for the response.txt for ok or error. Or polls it on a regular basis.
It's message passing between two different asynchronous processes where both can access a common folder. The common folder is the "mailbox" in the paradigm - and the files are the "messages".

I think I'd lean towards using smb to transfer the files since it would be so very simple to drop the pdf-file directly into the right place from wherever you want - if you set up a file share on the windows PC.

@Obsolesce I guess maybe instead of a webpage I could have some kind of PowerShell application running with a little GUI for the feedback?
Could you serve the same web page from the Windows box and have it do the printing?
Another possibility, use node or php to run a powershell script from the web page.
Otherwise yes, you could make a simple PowerShell GUI script to have the scanner enter the info and print. Then what? They would use that Windows box instead of the Mint box? -

From my prior research I found a webpage cannot print directly, served locally or not. The over all point of the process is the user scans a barcode and something prints, zero other interactions.

I think this could possibly work since the node or php "server" would be the machine itself. Brain didn't go the route of full local process.

I can easily print the PDF with Start-Process in a simple PowerShell script from the user machine
Because this is launching an actual process of whatever the default PDF viewer is I still would like something better than
Start-Processif anything exists. -

Start-Process.The only thing I can think of atm is keeping the Windows box logged on to, and running the process as the user or launching the process with ServiceUI.exe from within the PowerShell script.

I have no problem with this, the user will be logged in anyway. Just Start Process, with Adobe Reader as the default PDF application causes an instance of reader to launch and close. Taking focus from where ever the command came from. So far focus has come back to the windows that called
Start-Processbut I would prefer to be certain of it.So, I guess I'll deal with writing a little PowerShell application for this.

FYI, I cannot use Edge as the default viewer for this as it does not print correctly, I tried leaving that default.

ls file.pdf | Start-Process -verb printdoes not necessarily
depend upon a PDF reader at all. It is dependent upon the verb “Print” existing and configured in the registry for Explorer.exe configuration entries residing in the registry.- In Explorer.exe, navigate to any folder containing a file.pdf.
- Right click the file.
- Does the verb “Print” appear in the pop up context sensitive menu?
- if not, then you will get the behavior seen.
the Verbs “Open”, “Edit”, “RunAs”, and “Print” are windows Explorer.exe
