Sending Printer Data from Kernel Mode Driver

NTDEV
1

Hello,
I am writing a Bluetooth driver that acts as a printer server where a PC client can print to the host machine’s printer. My question is how should I handle the printer data that the driver receives from the client? Can I just send the data directly to the printer driver (I have the printer driver’s DeviceObject) or is there another way that I should send the data to the printer?

Thanks

Hi,

Considering that most of the Windows print subsystem now lives in
user-mode, it may be a lot easier to attack this problem from user-mode.
Perhaps something like writing your own user-mode service, passing it
the data from your driver via the “inverted call model”, and then
sending the raw data to the printer from your service. If you’re in
user-mode, you can send raw data directly to the printer with the
technique described here:
