I have been struggling with this issue for a long time: using 2.6 |
2 |
kernel, device /dev/lp0 swallow all input to it without error, and |
3 |
nothing comes out from the printer. |
4 |
|
5 |
example: |
6 |
$ dmesg > /dev/lp0 |
7 |
$ [no output on commandline, no output from printer, nothing happens] |
8 |
|
9 |
also cups running on this server shows every job is completed, nothing |
10 |
comes out in paper form. |
11 |

Here is the dmesg section that seems to be related to this issue: |
13 |
|
14 |
[ 5.293312] lp: driver loaded but no devices found |
15 |
[ 5.340515] rtc_init: no PC rtc found |
16 |
[ 5.380379] /pci@1f,0/pci@1,1/ebus@1/su@14,3083f8: Keyboard port at 1fff13083f8, irq 6 |
17 |
[ 5.472406] /pci@1f,0/pci@1,1/ebus@1/su@14,3062f8: Mouse port at 1fff13062f8, irq 7 |
18 |
[ 5.561939] parport0: PC-style at 0x1fff13043bc (0x1fff13047bc), irq 8, dma 0 [PCSPP,TRISTATE,COMPAT,ECP,DMA] |
19 |
[ 5.812374] parport0: Printer, Hewlett-Packard hp LaserJet 3015 |
20 |
[ 5.979388] lp0: using parport0 (interrupt-driven). |
21 |
|
22 |
from dmesg it seems kernel not only able to detect parallel port, but |
23 |
also possible to activate ECP mode and detect printer model (which is |
24 |
correct). I also have activated all kernel configuration options I can |
25 |
think of. I attached my kernel configuration file as well as whole dmesg |
26 |
output hoping that can help. |

The machine is Ultrasparc U5. It has been serving as print server for |
29 |
more then one year, or probably two years. |
