Fixing the Camera Printer

image
Ancient technology from the long long ago. The printer is the thing on top of the computer tower. The camera is the giant cabinet looking thing to the right of the monitor.

We have something called a “gel doc printer” at my work. It’s purpose is self-evident. It prints documents of our gel pictures.

Gel doc printers are used infrequently and often labs share them. Ours is shared between… probably five different labs? Maybe more.

Taking pictures of gels is important in science. Gels are how we visualize DNA and proteins.

A digital copy is good enough for your own records, but you need a printed copy in case someone claims your digital copy is edited. The gel doc printer provides that physical copy.

Our printer is shared and an issue comes up that when the printer breaks we don’t know whose responsibility it is to fix it.

Usually the breaks are fixed easily. A reboot of the printer or the computer will suffice. Not this time!

This time the printer has refused to print any and all images despite the computer recognizing it as a printer that is plugged in and printing test pages.

Awful looking test pages, but test pages none the less.

I delved into it and realized the printer’s driver’s were outdated. Normally this would be an easy problem to fix. Not so!

You see, the computer the printer is attached to runs Windows XP which is no longer supported by Microsoft.

An unsupported operating system can easily be hacked which means this computer can no longer be connected to the internet. If it was, hackers would have an easy access point to UC Davis’s systems.

What that means is I couldn’t just download an update to the drivers like usual. I had to download the update on my laptop and then move it over to the printer computer with my USB drive.

So I downloaded the drivers and moved them over to the computer. “But wait! You need the driver install program.”

Okay. I get that and move it over. “But wait! You need .Net Framework 4 to use the driver install program!”

Okay… I get that and move it over. “BUT WAIT! You need Windows Service Pack 3 to install .Net Framework 4!”

Okaayyyy… Move that on over. And that one finally installs!

Moving backwards, the .Net Framework 4 installed as well. Along with the patch I got for that.

Then the driver install program laughed at me and said it needed access to the internet after all. I tried installing the drivers on my own, but no luck there.

I researched more on the problem. The printer is able to print out the very first part of all the images. Then it disconnects from the computer, reconnects, and decides the print job is complete.

I found absolutely nothing on how to fix that problem. There were some suggestions that it was a problem with the connection to the computer, but switching the USB port used by the printer changed nothing.

Maybe a new USB cable would do the trick, but I’m unsure if those are available for printers this old or whether it would fix the problem.

For now, all the images are put on USB sticks and printed on different computers.
