Question USB Printer ("well supported") won't function


I've been playing around with a Epson Stylus Color 580, one of the "perfectly supported" gimp-print printers. I can't get it to work AT ALL.

So here's what does work:
1) I can see the printer in /proc/bus/usb/devices
2) I can see the printer in lsusb
3) dmesg reveals that the module is loaded,

Everything is great until I actually spool a job, then I get this in dmesg:

usblp.c: is on fire

The cable looks to be just fine, and I'm running 2.6.6 on Fedora 2. usblp.c is version 0.13, which is (I think) current.

Here's some of the outputs:

1) BEFORE PLUGGING IN (dmesg, last dozen lines)

In the spirit of disclosure, I feel I should mention that after extensive and exhausting googling, It seems that this exact problem also occured to another fellow while using the Paralell port. I wonder if there is some way to force a hardware reset on the printer?

When I first installed this printer, it began to spool a job, but due to my own stupidity, there was no paper in the printer. Now cups reports the error - "Media Tray Empty!" although it is not. Perhaps the printer is caching the error message and won't clear it?

In another bizzare twist of fate, I tried this printer on another computer, also with Fedora 2, but on kernel 2.6.5-1.358. The same message appears on that computer. I read someplace that USB printing support just isn't that good in Linux yet, but that seems like a cop out. Unfortunately, this printer only has USB, no LPT for me. I really need to get this working. Perhaps USB isn't communicating with the Printer FAST enough. How do I refine the max baud at which the USB cable will operate? Is that in usblp.c?

not sure which version of usb you are talking about.
but there is the deal.
usb v1.1 operates around 15mb/s
usb v2.0 operates around 400mb/s

This printer is being moved to a new computer from one who's PSU died during a storm. It is possible that the electricity touched the USB bus and shorted/damaged something in the printer?

then you probably need to contact the company right away and find your warranty material.
better get a new one or see if it still works on other system.

Resolution to this Problem: The printer was out of ink, and the driver will not allow any data into the printer without adequate ink. An incredibly lame ploy to sell more RGB cartridges when they really aren't needed.

I think the USBLP: on fire message was the kernel's way to telling me it didn't have a proper entry for the error code it was receiving. "Media Tray Empty" was a default error message, so that's what showed up in the GUI and under CUPS.

Hope my anguish can spare somebody else some trouble.
