PnP Manager installed the most suitable driver for an interface reported by your printer, in your case this was a USB class ID set to 0x7 which means a USB general printer.

Answers to your questions

  1. Generally no. Usbprint will handle everything if the printer conforms to USB printer class specification.
  2. I believe you need a user mode printer driver. Printer drivers are divided on the kernel mode and user mode part. The user mode driver is a dll loaded in the printing process.
  3. Usbprint works perfectly with all devices conforming to USB printer class specification. You need filter only if printer has some additional functionality.
