Years ago I had a HP deskjet. Huge cartridges. Cheap if you bought the refilled ones.
Power supply blew. It was on a seperate PCB and conveniently labelled as 18V output.
Fitted as socket & powered from SH laptop brick. Eventually sold it on to a friend.
Currently using an Epson. I now use a continuous ink system - a set of 100ml bottles of ink cost less than half a set of 12ml cartridges. With 6 disposable cartridges you would have the constant running out scenario, avoided with the continuous ink system although you do periodically have to 'pop-up' the cartridges to 'reset'.
About a year ago, had to fit a printer potty as the warning came up non-serviceable blotting paper is saturated! What a ridiculous way to limit the lifetime of a perfectly good appliance; you couldn't make it up.

The last time I had to replace a button, I used 6 pound test (monofilament fishing line).

In Northern Manitoba, I repaired boots that had exploded from too many abuses wading and portaging in terrible land where no one had stepped beyond.
That was some place in the Lynn Lake area, between Drybrough and Mc Gavock Lake.

Wondered when the single earphone first came out with the pocket transistor radio. 50's 60's or 70's.
Imagine using the single piece earphone on a 60s vintage AC/DC color TV!
I remember us having a smaller color TV with a hot chassis and my dad telling me to not use an earphone with it.

In those older sets, the earphone jack was isolated, because the audio was through the output transformer.
And to BKnut, yes, the 1958 Motorola, and many other 50's sets, both tube and transistor, had earphone jacks.
Saw lots of both types. Sometimes the crystal ones degrade badly, same as the phono cartridges.
The cheap Japanese two transistor radios seen in the early 60's used a novel "reflex" circuit to get the most out of two germanium transistors, one germanium diode, and a 9 volt battery. One transistor was the RF amplifier which drove a little ferrite RF transformer into a diode detector (AM demodulator). The recovered audio was then run back through the same transistor which also functioned as the audio driver stage. That ferrite RF transformer separated the RF and the audio which went to the volume control and then the second transistor which was the audio output stage.
I discovered that that same first transistor could also function simultaneously as an RF oscillator at 27 MHz. Even as a young kid I took stuff apart to see how it worked, and experimented on it. I took a quartz RF crystal from my Lafayette Radio Electronics CB walkie talkie, and poked around inside the radio with it. When it was placed from base to collector of the first transistor in the radio, the radio still played music, but the music also came out of a nearby walkie talkie!

The two transistor radios had a small speaker and an earphone jack. Most had the typical ceramic "crystal" piezoelectric earphone, but some did have a larger dynamic earphone (usually black or brown) which was not as loud. I can remember having them in primary school which was 1957 through 1964.
The real cheap 1 transistor radio also used the reflex circuit, but left off the audio output stage. These all had a "crystal" earphone, often hardwired in.
Most of the white or tan single (fat)earbud style transducers that I took apart were ceramic "crystal" types, primarily for efficiency reasons. You can still buy them:

The Lafayette Radio Electronics store was one of my hangouts as a kid. When my randomly assigned new novice level ham call sign arrived in the 80's it was KB4LRE. I still have that old call sign today even though I have upgraded my license to Extra class.
It's definitely nice to have a radio around, though usually the only thing I use it for is listening to NPR while I'm working.
The only place I listen to radio now is in the car. I can stream music to it, but I'm too lazy to bother so I listen to Ici Radio Canada or Radio 1.
At my dad's, I have an old 7 tube 3 diode radio set to 740AM. It works remarkably well if you can get the volume pot to conduct signal 🙂 It even works in the winter... It just takes longer to warm up.
EDIT: It's one of these actually - Nobody is actually paying money like that for these are they? Maybe I should care for it - I bought it for 7.99 at Value Village. Mine is beige.

There is a high price on nostalgia these days. Take a look at what a Scott 299 amplifier or a Dynaco ST-70 is going for. Crazy....
That radio listing has typical flaws - because it is NOT a "50's as they say, but early to mid 1960's - and likely made by National/Panasonic due to it's styling.
I have a similar one, a Panasonic model 740 that I use on occasion.
