USB Printer Device driver and IEEE Device ID string

mattlang — Mon, 28 Oct 2013 16:13:45 GMT

I have an MCF51JE256CLK that I made a printer device. It enumerates as a printing device and loads the standard kernal mode driver for printing on windows. USBPrint.sys. I can print to it by using the "Add Printer" Wizard for windows and open a USB001 port. But my device still lives in the unspecified category in "Devices and Printers".

What I would like to do is use an existing .dll user mode driver with a custom .inf and .GPD file. To my understanding, windows checks all the .inf files when a device is plugged in and finds the one with the best "rank". Would I be able to write an .inf file that makes windows pick my .inf file as the best one, and have the file point to an existing printer .dll and a custom .GPD? For example the generic text only driver or some PCL6 driver

My other question is: The PC never asks for my Device ID string that describes my printers capabilities such as manufacturer and PCL. When is the PC supposed to ask for this?

uint_8 printer_device_id[PRINTER_DEVICE_ID_STRING_SIZE] =
{
0x00,0x42, // Length of the Device ID string (MSB/LSB) including the
'M', // two length bytes
'A',
'N',
'U',
