Unless it is a 2.4.x kernel it can't do console on the line printer. Even if it does; it won't make the blaser talk; there are no flush codes. You need to put the blaser on a serial port and even then I don't know of anything other than emacspeak that supports the bns unless cvs speakup does. The blaser has old implementations of the bns speech code, but I believe it supports indexing. Doing an install of Linux with the blaser would also be rather bad since you have no way to shut up the speech, I've done installs like that and it gets old real quick especially when the kernel dumps 3k of messages out a port. If you can't shut it up somehow you don't want it for installs. One disk error will win you half an hour of speech you can't cancel, but do give it a try :-) Regarding shutting up speakup insert enter doesn't release the numpad and the review keys remain active. I was talking of a method to completely release certain consoles including the number pad.
