In the US, I would ask the neighbors, but given that our current relationship is still stuck at the "acknowledge existence if we accidentally run into each other" stage, it didn't feel appropriate.
First thing I tried was to resuscitate an old HP printer I had in the garage, but due to having been off for two years it decided that the (newly unwrapped)ink cartridges had expired and were no longer good. I popped out the battery that powers the internal clock, giving the printer amnesia and thinking it was the year 2000. Then it complained that the scanner was broken and wouldn't start up, so I disassembled the scanner, cleaned it, put it back together and... still the same error.
Then I remembered that I had an old Becker color ink refilling kit lying around that I had never tried out. It was for a different brand of printer, but I was desperate.
It came with:
- A metal pokey-thing for making a hole in the cartridge
- Three bottles of color ink
- Three syringes for inject the ink into the hole
- A set of rubber gloves
From now on, I'm buying my ink by the liter.
