So, first thing: printers typically attached to a parallel (LPT) port, not a serial (COM) port. A 25-pin port could be either, depending on if it has pins or sockets.
Secondly: these printers are a waste of time. They'll either be non-working and/or out of ink, and you'll be lucky to find any replacement ink for such out-of-date models.

As jmarsh said, the 25 pin port is actually parallel or LPT port, not a serial "COM" port.

Not sure you'll be able to find ink cartridges for those printers, although the first one seems to be dot matrix, which could make it easier to find a suitable ink ribbon that hasn't dried out by now. In any case, you should start by searching for the cartridges as that's probably harder to find in working condition than old printers.

And I have a 25 pin pink COM port and I would like to attach a printer to it

If it's coloured purple-ish pink (as per the PC-99 port colouring standard), then it's a highly likely to be parallel port, not serial. If it also has female pin receptacles, then it's even more likely a parallel port, because DB-25 serial ports have male pins.

Is plenty of cases where impact printing is still a thing today, for sure I served a company that still used them at least until 5/6 years ago, and we provided them with brand new Printers (Epson IIRC) and apparently they are still available as today, perhaps with USB/SERIAL/Parallel/NET connectivity, so no doubt about connectivity)

They aren't cheap for sure, but usually they are built to last "forever"

I though the port on the MB where pins and the port on the printer where sockets and a standard cable would fit both ends. Im sure there are countless places that sell ink cartages. If not are they powder, can you buy the powder and drill a hole in the old cartage to fill it

Old printers are a headache. You will probably have to disassemble the unit and lubricate the moving parts. Getting replacement ink cartridges is another problem. Plus they used scroll paper which I don't think is manufactured anymore. (Not a problem if you're just printing the odd page ofc)

If I were in your position I would get a parallel port laser printer like the LaserJet 1015. The ink for those is still widely available. They also still work with modern Windows via USB.

This would fit

The first two printers you posted use ink ribbons. The Seiko is a daisy-wheel printer, and the Star a dot-matrix printer. They work by impacting a letter form onto the inked ribbon, which transfers the ink to the paper (kind of like a typewriter). The third one, the Canon, is an inkjet (technically, a bubble-jet, because it's Canon) and uses liquid ink cartridges; they squirt ink through microscopic nozzles onto the paper.

You're getting mixed up with laser printers, which use toner powder (which some people mistakenly refer to as "ink").

It's highly unlikely you'll find ribbon or ink cartridges for any of them. And if you do find some old stock of ribbons, they may be dried up and useless, even if brand-new in an unopened package.

Edit: BTW, that Canon has a USB connection, and isn't parallel.

Yes its just for letters; 2 page max

are lazer jets the ones where the ink dose not wash off with rain water and stuff?

Will this one do the job?

Depending on the model you can buy everything still new on Amazon etc. I got a 37 year old matrix printer (Epson LQ-400) and just bought new inkt ribbons and a pack of continuous feed paper. Also almost all matrix paper will print on normal A4/letter paper without problem.

I use it with a HP JetDirect 170X parallel print server and can use it from DOS all the way to Windows 11 without problems. To be clear I use my laser printer most of the times but it is still very usable if you don't need better quality prints (or don't like the sound 😀). Inkt ribbons are much cheaper than laser printer refills.

The cannon one (the last one) looks like its a parallel to a USB cable. apparently only 4 of the 25 pins are used on the parallel port. + & - 5V and two signal wires, as you can see from the photo there is no transformer in that cable. A replacement cable should work

Google states the following
The Epson LQ-400 is a classic 24-pin dot matrix impact printer introduced by Epson as a more compact replacement for the older LQ-800 model

My port is 25 pin not 24!

You mean like these 2?

As others have said, it's a parallel (LPT) port, not a serial (COM) port. Printers with serial ports do exist, so it's important to know the difference. You want parallel.

And get a dot matrix printer. Epson LQ series or something similar to it. You might have to clean the pins with a little alcohol and get a new ribbon but other than that they should work fine as opposed to old inkjet or laser printers, which are much more complex.

Also your confusion about the 24 vs 25 pin is because you don't realize that "pins" on a dot matrix printer is referring to the number of striking "pins" in the print head, not the number of electrical "pins" in the parallel port. No printer is ever going to say how many pins are in its parallel port, because it is always 25.

The 24 pin here is referring to the print head, not the parallel port.

Just to confirm its a 25 pin port on the MB

dot matrix printer ribbon powder right? And laser is ink?

This 24 pin thing you mention makes no sense!

Thanks! I get it now. But that printer is a 25 pin parallel port right?
