Comment 25 for bug 959676

using 1.5.3-0ubuntu2~ppa3 both with and without the blacklist the printer behaves the same as before: data light flashes for 5 minutes (exactly 5?) and then returns to steady indicating it's default idle state.

After removing the blacklist file and loading the usblp module the printer is not recognised as plugged-in with cups reporting "Idle - Waiting for printer to become available." However trying to print to it anyway changes the state to "Processing - Sending data to printer." and the data light flashes as described above. dmesg, after removing the blacklist, reports

[ 3450.780442] usbcore: registered new interface driver usblp
[ 3749.481242] usb 4-3: USB disconnect, device number 2

the last line occurs as I try to print.
