23.9.3 Parallel Ports
The safest approach is to connect the printer directly to the first parallel port and to select
the following parallel port settings in the BIOS:
• I/O address:
378
(hexadecimal)
• Interrupt: irrelevant
• Mode:
Normal
,
SPP
, or
Output Only
• DMA: disabled
If the printer cannot be addressed on the parallel port despite these settings, enter the
I/O address explicitly in accordance with the setting in the BIOS in the form
0x378
in
/etc/modprobe.conf
. If there are two parallel ports that are set to the I/O ad-
dresses
378
and
278
(hexadecimal), enter these in the form
0x378,0x278
.
If interrupt
7
is free, it can be activated with the entry shown in Example 23.1,
“/etc/modprobe.conf: Interrupt Mode for the First Parallel Port” (page 454). Before ac-
tivating the interrupt mode, check the file
/proc/interrupts
to see which interrupts
are already in use. Only the interrupts currently being used are displayed. This may
change depending on which hardware components are active. The interrupt for the
parallel port must not be used by any other device. If you are not sure, use the polling
mode with
irq=none
.
Example 23.1 /etc/modprobe.conf: Interrupt Mode for the First Parallel Port
alias parport_lowlevel parport_pc
options parport_pc io=0x378 irq=7
23.9.4 Network Printer Connections
Identifying Network Problems
Connect the printer directly to the computer. For test purposes, configure the
printer as a local printer. If this works, the problems are related to the network.
Checking the TCP/IP Network
The TCP/IP network and name resolution must be functional.
