v4 printer driver

Question

Hi,

I have a few questions regarding v4 printer drivers...

1. whether the template provided for xps filter is functioning , by functioning i mean do it send data to the port monitor for printing.

2. If no then how to redirect data from filter to port monitor.

The problem i am facing with v4 printer driver is, it's not sending data to the device for printing although there is entry in print queue and it shows status spooling and printing.(i am using the xps filter template as it).

Thanks

Hi Arshdeep,

The template does not write data to the output buffer (you can see the output buffer in the variable m_pWriter). You can get it to write to the filter pipeline (which will take care of routing to the port) by writing to this. If you need an example of a fully functional XPS rendering filter, I'd recommend having a look at the XPSRas filter sample. http://code.msdn.microsoft.com/windowshardware/XPS-Rasterization-Filter-05aa56dc

Thanks!
