I don't have any .tar files labeled as "plugins", but this is what I have:
http://k.minus.com/jbmwkXBVyT7XTF.jpeg . If you want one of these, let me know.
I was wondering if you would know what or where the file would be for me to take off of my machine that the plugin would be installed as. I have had to do this before and it worked, but I can't find that file now. This changed about a year ago.
For example, the plugin used to be located here, /usr/share/foo2zjs/firmware/sihp1018.dl , but where the downloaded file is now, I do not know. For some reason, about a year ago, I had to run this command to reload the firmware "[root@localhost user]# cat /usr/share/foo2zjs/firmware/sihp1018.dl > /dev/usb/lp0" after it stopped working. But now this file is not there, but it has not stopped working either.
Update, I just went to visit this location and sure enough the firmware is there and it is dated 6-17-11. You may want to try and drop the firmware in the proper location, then run the command above, and see if it works. If the firmware loads, then the printer should make a loading sound.
I have placed the firmware here:
minus.com. Let me know if you have trouble getting the file. I would try the command above to see it it works. You may have to alter your folder and/or printer mount location.
I hope this helps.
Edit: clarification
