2.2.xx ? messages related to parport printer ?

[Jean-Luc Coulon]

Hi,

I've an Epson Stylus Color 500 and at boot time I've the following
messages :

with 2.2.20pre (and so well with 2.2.xx) :
------------------------------------------
May  9 13:14:54 debian-f5ibh kernel: parport0: PC-style at 0x378
(0x778), irq 7 [SPP,ECP,ECPEPP,ECPPS2]
May  9 13:14:59 debian-f5ibh kernel: parport0: Unspecified, EPSON Styl
May  9 13:14:59 debian-f5ibh kernel: lp0: using parport0
(interrupt-driven).

With 2.4.4-ac6 and 2.4.xx, I get :
----------------------------------
May  9 14:19:42 debian-f5ibh kernel: parport0: PC-style at 0x378

May  9 14:19:44 debian-f5ibh kernel: lp0: using parport0
(interrupt-driven).


... parport0: Unspecified, EPSON Styl
why is the message truncated -------^  ?
what means "Unspecified"               ?

Huh.  Does it do the same thing every time you load parport_probe?
Does it always get truncated in the same place?

Well, at least it seems to work in 2.4.x.

I wonder what deviceid makes of it:

Yes ! :-/

[jean-luc@debian-f5ibh] ~ # modprobe parport_probe
parport0: PC-style at 0x378 (0x778), irq 7 [SPP,ECP,ECPEPP,ECPPS2]

MFG:EPSON;CMD:ESCPL2-00;MDL:Stylus COLOR 500;CLS:PRINTER;

There is an other strange thing : escputil expect "Stylus Color" and
my printer send "Stylus COLOR" (uppercase)...

Nothing really uses that information in 2.2 anyway, so it's harmless
at least.  It's probably a timing thing; take a look at the
differences between the 2.2 and 2.4 code for that.
