[SOLVED] Slackware-13.1 and foo2zjs

business_kid · 09-23-2010, 02:31 AM

They've changed something on slackware-13.1 around hotplug and I'd love to know what. As part of installing foo2zjs - a printer driver for things that talk in zjs, a hp protocol, there's a

make install-hotplug step.

This makes a directory /etc/hotplug/usb and populates it with symlinks and a script. The script loads firmware and the symlinks refer to any printer it covers, so in fact it should bang in the firmware, but this is not happening on slackware-13.1

Now it's all probably done with hal, dbus, or some other "utilities" that nobody can get their head around. Can somebody tell the guys there we speak English, not xml :-/?

It isn't clear if you are asking for help about something or venting.

Sorry about that.

I'd love some help on this. It's not running the script in /etc/hotplug at all, afaict. Now I know hotplug was trailing edge technology, but I'm not sure what's going on in place of it.

I can bang a command into rc.local, but that does squat if I come along later with the printer. Ideally wherever it figures out there's now a printer online, I need to get it to send down a bit of firmware.

Well, I think that part of it would be handled by udev and another part by hald.

I think that /lib/udev/rules.d/70-printers.rules should give you an idea of what to do. You'd have to add your custom rule to /etc/udev/rules.d directory and use the RUN+= udev directive to run the command to send the firmware to the printer.

I haven't done any of this myself (hey, those who can, do, etc), but I think this would be the way to do it. :-)

No quick fixes here. Apparently /dev/usb/lp0 is more than a little reluctant to make an appearance. I tried a command like you suggested.
No dice. Did nothing or error > /dev/null.

So I got crude: in modprobe.d/printer.conf
install usblp = "/sbin/modprobe -i usblp && pause 10 && /usr/bin/cat /lib/firmware/sihpP1005.dl > /dev/usb/lp0"
That throws a number of firmware packages at the printer when I remove the module and plug plug in the printer. Can I improve on that?

Maybe you should look at http://www.reactivated.net/writing_u...l#external-run

You may have to write a wrapper script.

(OT: I wish the bleeping URL popup did NOT come with the http:// prefix filled in. That really interferes with X paste. Grr.)

Here is what I tried for my Laserjet 1020:

The make install-hotplug script doesn't work because /lib/udev/rules.d/70-printers.rules is there. So I moved it somewhere else, ran make install-hotplug, then put the file back in place. It seems to work now, although I didn't do extensive testing.

In the foo2zjs directory there is a file hplj10xx.rules. In that file there are udev rules for the printers, like

Code:

#Own udev rule for HP Laserjet 1020
KERNEL=="lp*", SUBSYSTEMS=="usb", ATTRS{idVendor}=="03f0", \
        ATTRS{product}=="HP LaserJet 1020", NAME="usb/%k", \
        SYMLINK+="hplj1020-%n", MODE="0666", RUN+="/etc/hotplug/usb/hplj1020"

for HP LJ 1020 and this file goes into /etc/udev/rules.d. In fact I had this file already in place from my previous foo2zjs installation, but probably in the new version some symlinks etc. have changed and they were not fixed until I was able to run make install-hotplug.

Thanks.
I'm 'spoken for' today. I'll get to this and come back.
I have 2 installations - one with /lib/udev/rules.d/70-printers.rules and one without. I'll get to this later and report back

Works for one of the boxes here - the 32 bit.
I think I'll need a closer investigation on 64 bits, but that's nothing new :-/.
