It looks like your problem occurs either as a result of the USB printer driver's actions or as a result of HAL. You could try turning off the HAL daemon and renaming the usblp.ko file so that it won't get loaded automatically. Then after plugging in the printer you could insmod the renamed driver file by hand, and see whether that causes the oops. Then start HAL by hand and see whether that causes the oops.
