Parallel Port Problems
 
I'm trying to use a parallel port printer, but am having little luck so far.

Part of the lspci -v output is as follows...

00:08.0 Parallel controller: NetMos Technology PCI 9865 Multi-I/O Controller (prog-if 03 [IEEE1284])
Subsystem: Device a000:2000
Flags: bus master, medium devsel, latency 64, IRQ 5
I/O ports at efa0 [size=8]
I/O ports at ef88 [size=8]
Memory at febf7000 (32-bit, non-prefetchable) [size=4K]
Memory at febf6000 (32-bit, non-prefetchable) [size=4K]
Capabilities: <access denied>

Aaargh! How do I get access?

You're trying to use a parallel printer? Yes you have problems.. :p


All joking aside, this may be as simple as the kernel module not being loaded.


I found an LQ blog posting which should help you get the big picture:

Verify that the module is loaded and then you should be able to either add it with the cups GUI or manually into the cups config file as a printer.

Also be sure to look at any bios settings that might affect this.

/Thinking back 10 years

There was lp.ko and parport.ko in the kernel - lp.ko was for printers (theoretically no talkback) and parport.ko for bidirectional (Parallel ports have 8 output and 5 input lines). You need one or the other, not both. You now also need things now bundled off in the kernel for ease of ignoring them. In the device drivers section, look for something like 'legacy crap' or 'lost, obsolete and forgotten drivers' and go looking for parallel port stuff in there. If it's enabled, you're ok. If not, you may have to build.

i/o card, parallel printing - are you running a museum? :-).
