I read some articles suggesting that in order to make printer work, the |
| 18 |
parallel port need to work in ECP mode, the cable has to be IEEE1284 |
| 19 |
(bidirectional). |

1) I don't know how to check if the port is in ECP mode. I used to check |
| 22 |
it with BIOS utilities on x86 but I don't know how to get this info on |
| 23 |
sparcs. A quick google search with 'ECP OBP' doesn't give needed info. |
| 24 |
2) I don't know how to test the cable if it is bidirectional or not. But |
| 25 |
I thought it is difficult to get a unidirectional cable, so it might |
| 26 |
be... |

How do you suggest? Thanks in advance:) |
