 Posted: Fri Mar 23, 2007 10:31 pm Post subject: Still can not detect the parallel port [SOLVED] |
 |
|
The problem persists and it seems to be all over the Internet.
Linux can not detect parallel ports whether printers or scanners, etc are connected. Can you help?
I have installed Gentoo 2.6.19 (3/20/07)and used genkernel to configure the kernel. I followed all the instructions. The install went well and the Linux os(hdd1) and Windows XP(hdd0) share the same box and dual boot nicely. The printer works great under Windows and the parallel port is not even detected under Linux. I used the manual config on the kernel and either modularized or accepted all the found choices under Devices and Character and then used make and make modules before copying the compilation to /boot. I still have no detection of lp0 and I'm not sure the modules are loaded. I changed grub to point to the new compilation in boot and still it doesn't work. I even checked the BIOS for the computer and PnP is not on but I am using ECP instead of EPP. I am hesitate to change the BIOS until I know how it will effect Windows. Since this problem has existed for 3 years around the internet I would assume a good and easy solution would be available. I even tried the script ppdiag and it gave up since the parallel port is not detected.
I could use and would appreciate some help as myw ife needs to print a paper for Mondya (3/26). Thanks alot. C

You probably need those options (not sure though, as I never had to use a parallel printer under Linux, my only use of the port is to connect a JTAG interface):
| Code: | Device Drivers --->
Parallel port support --->
<M> Parallel port support
<M> PC-style hardware
Character devices --->
<M> Parallel printer support |
The modules are named "parport", "parport_pc" and "lp".

Just note the old settings somewhere so you can put them back if there is anything strange happening. I guess Windows will be able to adapt... |

| Those modules are marked for installation and I did change my BIOS for an experiment but it did not solve the problem. I don't think the modules are being utilized by grub during startup. Could I be missing a step in installing the new kernel config into grub for bootup. |

But are they actually loaded (check with lsmod) ? If they're not, try:
| Code: | # modprobe parport
# modprobe parport_pc
# modprobe lp |
If it works, then add the modules to /etc/modules.autoload.d/kernel-2.6 so they are loaded automatically at startup. |
