View Full Version : parallel printer with hot plug

18th April 2011, 04:49 PM
When I boot fc14 with an already defined printer connected on the parallel port, then I can use the printer. The printer appears on parallel:/dev/lp0.

But, if the printer is not connected during startup, when I connect the printer I cannot use it. Nothing happens. I have no corresponding message using "dmesg" command when I connect the printer.
I cannot make cups see that the printer is connected, using "localhost:631" in firefox...

Is it possible to "mount" the printer manually ?

I think that I solved the problem.

Using "system-config-printer", the printer has to be "activated", even though it is not used or even connected.
Then "parport" module is installed during boot (with other related modules: "ppdev" and "parport_pc").

Then, when the printer is connected, "dmesg" shows :

lp0: using parport0 (interrupt-driven).
lp0: console ready

And, of course, it is now OK to use the printer.

Well, today it is not working !

parport module is loaded but when I connect the printer, I get with "dmesg":
"lp: driver loaded but no devices found"

... ?
