SOFT_RESET (bRequest = 2)
This class-specific request flushes all the USB buffers and resets the Bulk OUT and Bulk
IN pipes to their default states. This request clears all USB stall conditions. This reset
does NOT change the USB addressing or USB configuration or actually reset the printer.
Note:
Version 1.0 of the USB printer class specification incorrectly stated that
the bmReqestType for SOFT_RESET was 00100011B.
EPIC 3000 USB Interface
The EPIC 3000 USB interface supports all three interfaces. The Get Device ID interface
is configurable and may be disabled to prevent the host operating system from
attempting to automatically install a Print Driver

.
Note:
The Print Driver is not the USB printer driver. It is a higher level driver
that may or may not be used in the host system.
The Soft Reset will not reset the operating firmware nor will it do a complete hardware
reset. It only resets the USB bulk pipes.
23
The Print Driver is not the same as the USB Printing Support Driver. The USB Printing Support
driver supports the USB interface but does not provide print services. The Print Driver provides a
printer specific API on top of the USB Driver.
