I did some tests with printing yesterday.
If I enable DEBUG in drivers/parport/parport_amiga.c, 
printing works.
The only problem is that a page containing only one letter is printed
out after it's done with what it was supposed to print out.

Without DEBUG disabled it only prints garbage (when printing postscript
files).

So, I thought maybe it tried to send data faster than the Amiga
parallell port (or the printer) could handle or something. (since
writing the debug output will add a short delay)

So, I turned off DEBUG and added a for-loop inside
amiga_write_control(..)
to add a small delay, and printing still worked...

Timing problem ?


the config used (from memory, so it may not me the correct names)
CONFIG_PARPORT=Y
CONFIG_PARPORT_AMIGA=Y
CONFIG_PRINTER=Y

CONFIG_M68K_PRINTER does not work as that needs some functions found in
lp_m68k.c which we don't have in 2.4.
