I want to know whether, I can use LoadLibrary() and GetProcAddress() API

I have a Dll Which performs printing task. I want this dll call to be used
in my Virtual Drivers. Is it possible to use directly or there is some other
way around to perform this task.
I want to use this dll calls when write Request will arrive to the virtual
Driver.
LoadLibrary and GetProcAddress are user-mode APIs. Kernel drivers cannot
call user-mode APIs. If your DLL is a user-mode DLL, as it almost
certainly is if it does printing, then it cannot be used in the kernel
either. You need to have a user-mode helper process or service to do your
printing.
