Well your experience seems to indicate that udev is the problem. It occurred to me that maybe I don't see a parallel port option in cups because I don't have a parallel port on my machine.
But why does Karl not see it when he has a parallel port?
Good question Aaron. This thread has been going on so long now that I'm tempted to build me a kernel with the parport driver, which I haven't for years because I have no parport device, having found that my elderly C82 runs faster on a usb port.
However, in my case I really wouldn't expect to see a parport option even available at step 2 of the modify printer from the cups web page procedure.
However, even though I have no parport support in this 2.6.23-rc2 kernel, I see that udev has indeed setup a list of them. This, except for gutenprint being pinned at 5.10, is an uptodate machine as of yesterday:
[root@coyote clips]# ls -l /dev/p* lrwxrwxrwx 1 root root 7 Aug 6 09:13 /dev/par0 -> usb/lp0 crw-rw---- 1 root lp 99, 0 Aug 6 09:13 /dev/parport0 crw-rw---- 1 root lp 99, 1 Aug 6 09:13 /dev/parport1 crw-rw---- 1 root lp 99, 2 Aug 6 09:13 /dev/parport2 crw-rw---- 1 root lp 99, 3 Aug 6 09:13 /dev/parport3 crw-r----- 1 root kmem 1, 4 Aug 6 09:13 /dev/port crw------- 1 root root 108, 0 Aug 6 09:13 /dev/ppp crw-rw-rw- 1 root tty 5, 2 Aug 8 08:03 /dev/ptmx
Which I find interesting, and would consider udev's making them a bug when there is no driver available to be driven. And given that they are there, I would have to assume cups would offer the option...
From the .config that built this kernel:
# CONFIG_PARPORT is not set
I also have the same parports that you have and there is no parallel port on my machine. I would conclude then that udev is nto the problem but cups is. However, we are getting conflicting reports on this matter.
For anyone who is interested, the problem regarding the parallel ports and printing appears to be a udev problem. A udev update addressing this problem has been pushed out. A couple of hours ago, I received the following announcement:
-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2007-1491 2007-08-08 08:34:06.263874 --------------------------------------------------------------------------------
Name : udev Product : Fedora 7 Version : 113 Release : 9.fc7 Summary : A userspace implementation of devfs Description : The udev package contains an implementation of devfs in userspace using sysfs and netlink.
-------------------------------------------------------------------------------- Update Information:
re-adds /dev/lp* device nodes -------------------------------------------------------------------------------- ChangeLog:
* Wed Aug 8 2007 Harald Hoyer harald@redhat.com - 113-9 - added lp* to 50-udev.nodes (#251272)
--------------------------------------------------------------------------------
With any luck, this will resolve everyone's problems with CUPS parallel port printing.
