I am having a similar problem however as I compiled my C++ code on windows10/cigwin /32 using CodeBlocks and while using the debugger having it 'crash' on the OpenPrinter() function I am searching for an answer also.
I have used a similar code and compiled it on Windows7/Borland and have had no issues printing from a browser url to the local machine using a browser http ref : protocol.
After upgrading to windows10 I am finding that the old program is being "Url Invalid" for the url hence the reason for the upgrade.
The error I am getting is "SIGSEGV segmentation fault, error message -1073741819 (0xC0000005)" but I am not able to locate where the problem lies.
What does Windows say is happening?
Enable the PrintService/ Operational events
Open Event Viewer
Applications and services
Microsoft
Windows
PrintService
The Operational events are not enabled by default so turn on this event level and execute your code again.
One other point, does the printer support the text datatype? It absolutely does not support PDF as a datatype.
If you call the driver, then the driver should be converting the text or PDF into PCL which the printer supports.
