Martin - my system supports 4 parallel port modes: output only, bi-directional,
EPP and ECP. None of the settings cause any change in the behavior of cupsys
("no printer found"). I added comments (;) to my terminal output:
[EMAIL PROTECTED]:~$ dmesg|grep lp0 ;Output only mode
[4294688.737000] lp0: using parport0 (interrupt-driven).
[EMAIL PROTECTED]:~$
[EMAIL PROTECTED]:~$ dmesg|grep lp0 ;Bi-directional mode
[4294689.781000] lp0: using parport0 (interrupt-driven).
[EMAIL PROTECTED]:~$
[EMAIL PROTECTED]:~$ dmesg|grep lp0 ;EPP mode
[4294692.569000] lp0: using parport0 (interrupt-driven).
[EMAIL PROTECTED]:~$
[EMAIL PROTECTED]:~$ dmesg|grep lp0 ;ECP mode
[4294688.682000] lp0: using parport0 (interrupt-driven).
[4294764.613000] lp0: ECP mode
[EMAIL PROTECTED]:~$
Also, my BIOS allows 3 separate parallel port states: disabled, enabled (select
I/O, IRQ & DMA) and auto. Again, choosing between enabled and auto made no
difference.
