Background
I have a very old
EPSON R300 inkjet printer
It has served me well for many years. I thought it was at least 10 if not 15 years old. I got it before I even became interested in Linux. For many of those years now I have been using this printer extensively on Linux.
It has been a really good printer and has been incredibly cheap to run. Many years ago I got a number of sets of ink for it. I think they only cost me £15! A colleague at work later on gave me more sets of ink. I ended up with a large bag full of ink cartridges which I have been working my way through ever since.
I used the printer infrequently for many years. This is far from ideal for an ink jet printer as doing so tends to cause the ink jet nozzles to clog up. Unsurprisingly in later years it has become somewhat temperamental. The problems consisted of paper mis-feeds (Probably down to the rubber take up rollers going hard over time) and missing bits of print (This I assume due to infrequent use of the printer and age of ink jet cartridges all of which were well out of their expiration date).
The mis-fed paper could be solved by individual feeding each sheet through the printer. The poor / missing print could be solved by a combination of running the print head clean routine or by replacing the offending cartridge.
Latterly I had print problems again and as per usual after cleaning the heads and then finally changing the cartridge the printer resumed printing normally.
Shortly after this I bought myself an Apple iMac mini and thought it could be useful to be able to print from it. I visited the EPSON website downloaded and installed the EPSON print driver for my trusty R300 printer.
I tried printing from my iMac and received a warning stating something like some of the components within your printer are worn and may need servicing. I’d never seen a message like this before as I normally print using open source print drivers on Linux which never report such things.
When I tried printing on my Apple Mac no black text was visible on the page. I tried running the head cleaning routine and this made no difference. I eventually had to resort to changing the colour of the text within the LibreOffice document. This allowed me to print text that was at least legible.
At the time I was a little suspicious of all this as the printer had been working so well just a few days previous. I plugged my trusty printer back into my trusty PC running an old version of Ubuntu using the open source printer drivers. Fired up LibreOffice and tried to print a document. To my surprise the printout was very good. While it was not as good as when the printer was new the quality of the black and coloured text was actually very good.
My suspicion though I can’t prove it is that the EPSON print driver has worked out that the printer is 10 plus years old and needs to be returned to EPSON for servicing (or to purchase a new printer). To ensure this the driver is crippling the output from the printer.
The Open Source print drivers have none of the nefarious nonsense and allows the printer to operate. As I said I cannot prove any of this however I’ll leave this up to you decide what you think is going on here.
At this point I was going to end the podcast however the story didn’t end there.

In our next look at the game mechanics for Civilization V we examine the topic of Science and how to win a Science victory. This is something that has been in Civilization from the very beginning, but in Civilization V there are some changes worth addressing.
Playing Civilization V, Part 7
Science
In most respects this is not all that different in Civ 5. Most of the techs are the same, there is a tech tree that is pretty similar, and you need to keep up in Science for any victory condition you are seeking. You may want to just beat your enemies into submission, but if you are using Chariots while they have Tanks, you aren’t going to have success. But also it is obvious that if you are going for a Science victory, you need to really focus on this. So many of these tips should be followed for any victory condition, but should be mandatory if you are going for a Science victory. The mechanics of researching technologies is that you have to accumulate a certain amount of Science to discover a new technology, but this amount goes up over time, so you have be continuously looking to increase your output of Science to keep up. for instance, one of your first Techs would be Pottery, which has a cost of 35 Science. But in your Capital city you get 3 Science from your Palace, and let’s say you have a population of 2, so you are generating 5 Science per turn. That means you will research Pottery in 7 turns. But the Education tech costs 485 Science, Astronomy costs 780, Scientific Theory costs 1650, Plastics 4700, and Particle Physics 6000. These are all key techs to advance your Science to a Science Victory. So you can see that you need to be continually increasing your Science.
To start with, Population=Science. You get one Science for every one point of population. That does not, however, mean that you need to have a lot of cities to get there. 4-5 well developed cities are quite sufficient, and adding more cities can cause Unhappiness problems. Since higher population itself can cause Unhappiness there is no good reason to add to the problem.
Buildings
The next boost you can give to Science is by building city improvements. The first, which comes early in the game, is the Library, which is available once you research Writing. A Library boosts the Science output of a city by one Science for every two citizens (roughly a 50% boost, rounded down), so building those early pays off. Because advancing through the tech tree is a process of accumulating Science, the earlier you can get these boosts the better. The other population-based boost is the Public School (available when you research Scientific Theory), which also boosts Science by one for every two citizens, and also offers a Specialist slot for a Science Specialist. And since more population means more Science, the Granary (available when you research Pottery) is a good building because it helps to grow your population.
There is one other building worth mentioning which is the Observatory (available when you discover Astronomy). It doesn’t depend on population, but on location. You have to have a city that is located directly next to a Mountain to build this, but it adds 50% to the Science output of the city. Mountains are otherwise useless (unless you are the Incas), but if you want a Science boost and happen to see good location (the ideal spot is an isolated mountain that is not part of a mountain range so you don’t lose farming and mining production) this can be great boost.
Scientist Specialists
You can at a certain point take some of your citizens out of the farming and mining and turn them into Specialists, but you have to have a slot for them, and those slots come in buildings as well. We’ve already mentioned Public Schools providing one slot. Universities (available when you discover Education) provide 2 slots, as well as boosting the city output of Science by 33%. The other S
