Printing from C++ application

[PeterKrall]

I am trying to print from a C++ (MSVC) application. I see the document in the printer queue but it vanishes without printing as soon as EndDoc() is invoked.

Printing to PDF works. Also, I can print to the HP printer from Word or other applications.

The printer is a HP Envy 5030

The code previously worked on a Win 7 system

Maybe I need to install some driver? But which and how?

You should try asking around in a programming forum for advice on this one.  We wont be able to assist you with any custom built apps.  As long as the printer can print a test page from the printers and scanners area then you know the printer is installed correctly.  Anything else after that is a compatibility issue between your custom app and the currently installed driver.  Inkjets do not work well with Universal drivers so you are most likely limited to the current driver on HPs support website for your model and OS.

Here is a thread where some developers troubleshoot C++ printing issues:

You can always flip drivers around and try new ones.  There is no harm in creating a 2nd test queue and play with whatever drivers you want.  There is also no way to know what driver is compatible with your app without trial and error.
