My printer is connected through USB, so I used the method from comment #56. Once I bothered to turn the printer on, I found it under /dev/usb/lp0. When I send the files to the printer using cat ..., in both cases it took 65 seconds to transfer. I did not see the keyring warning. Neither file printed anything, until four minutes later, when the ERROR: invalidaccess message came out again. This was just like using the lpr -oraw method.
