Printing

[Ken T. <ke...@we...>]

Looking through drivers/char/lp.c I see a mention of buggy handshake
fixed on epson stylus color, of course I have one of these and I can't
print under 2.4.8.

Can anyone print under 2.4.8 APUS or m68k or am I just the 'lucky' one ?

Ken.

No, printing is broken on APUS. (If this hasn't changed recently)...

On my system printing in 2.4 works quite well when DEBUG is enabled in
parport_amiga.c, but others have tried that without so much luck.


Actually the generic printer driver don't work in 2.2 either. (just
remembered this...).
As you may remember when compiling a 2.2 kernel you need to enable
CONFIG_M68K_PRINTER, but not the parport or config_printer...
It looks like the 2.2 printing code (lp_intern.c and lp_m68k.c) completely bypasses the amiga parport driver
(parport_amiga.c).

I tried adding these files to my 2.4 tree, but didn't get it working. I had
to change a couple of lines to make it compile, and maybe that broke
something, or there is something else I forgot about. It prints the first 2
characters, and then goes busy...

DEBUG works for me two.

I used CONFIG_M68K_PRINTER in 2.2 and printing was fine, I never
discovered the problems.

yes, that's what I said (well, what I meant to say anyway)...
This appears to be the case in 2.2:
when config_m68k_printer is set, printing works fine (the code in lp_m68k.c
and lp_intern.c is used).
If you instead of setting config_m68k_printer=y, set config_printer=y and
config_parport_amiga (or whatever it's named) = y, it will use the code in
lp.c, which in turn uses parport_amiga.c functions to send data to the
printer. This is the same as in 2.4, and does not work properly...

Yes, lp_intern and lp_m68k predate the generic parport subsystem.
