OK, I tried that (though it turns out it wasn't the problem, see below). |
| 15 |
I'm glad I wrote down my about-to-be-deleted config first. localhost:631 |
| 16 |
has got to be the cruddiest GUI configurer around. I think I had to |
| 17 |
describe my (USB connected) printer as "scsi", and then a little later |
| 18 |
had to enter a "NAME", without any indication being given of whose name. |
| 19 |
Luckily, I have enough experience to guess correctly, 'cause there's no |
| 20 |
help on these things. How I hate cups! |
| 21 |

My actual problem was that my printer is on /dev/lp0, generated by mdev. |
| 23 |
When I switched back to a udev system, the printer's on /dev/usblp0 |
| 24 |
(which is a symlink to /dev/usb/lp0). |
| 25 |
|
| 26 |
There doesn't seem to be anything in any cups config file to specify the |
| 27 |
device to print to. The nearest thing to a config item is |
| 28 |
|
| 29 |
DeviceURI usb://Samsung/ML-1450 |
| 30 |
|
| 31 |
in /etc/printers.conf. I don't know where "usb://" is defined - Firefox |
| 32 |
rejects it straight off. I don't know how this URI is converted to |
| 33 |
/dev/usblp0, but it seems to be hard coded in effect. |
| 34 |
|
| 35 |
So, can I configure "usb://Samsung/ML-1450" as /dev/lp0? |
