You *should* be able to query the 1284 Device ID string using the cupsSideChannelDoRequest API. See the CUPS documentation on how to use that:

	http://www.cups.org/documentation.php/api-filter.html

However, many operating systems' parallel port drivers have bugs with this so it is better to provide a PPD file matched to the device ID so that you can look it up in the PPD instead of querying the device at print time.
