Yes human, this thing still counts as a cat bed.

Mostly white long hair cat on an old dot matrix printer; he's looking at the camera.

Also delivered were two wide-format dot matrix tractor feed printers!

These things are in rough shape: the foam padding is crumbling to dust, there's metal plating flaking off the rods, and they're just generally full of dust and debris and undoubtedly spider eggs. My relative insists that they work, though. When pressed, they explained that they worked perfectly thirty or forty years ago.

[Edit: forgot to add the pictures.]

A photograph of a Dataproducts wide-format dot matrix printer. It's dusty, and the plastic protective film over the buttons on the front has turned brown and cracked and flaked away.

A photograph of another wide-format dot matrix printer, also dusty and full of debris, but looking to be in better condition. This one has no badge on the front, but the type plate on the back shows that it's a Toshiba P341SL.

J'ai réparé mon imprimante matricielle ! 🎉
C'est une Star LC-10, elle imprimait un début de ligne et le chariot se bloquait avant que l'imprimante ne se mette en erreur.
J'ai vérifié l'alimentation, la commande du moteur du chariot, RAS.
Au final c'était un problème mécanique, j'ai graissé les éléments mobiles du chariot et j'ai fait tourner le ruban encreur dans sa cartouche avec une visseuse électrique, et ça m'a l'air bon maintenant !
Testé avec mon #Atari Mega STE et le traitement de texte Papyrus (et pas la bonne fonte!)

Specifications for the Epson LX-80 dot matrix printer from its manual. In 1984 these were fairly typical for 9 pin printers, though things like Near Letter Quality mode were less common (a mode that increased the effective resolution of each character: normal mode characters had to fit in a 8x9 grid, while NLQ characters had a denser 12x18 grid for the same size - this allowed 9 pin printers to stay relevant a bit longer though at the cost of printing speed).

While I did order a new oooold stock ink ribbon cartridge for my printer, I decided to try the WD-40 trick to revive an old ribbon.

Verdict: it mostly works!

#dotMatrix #WD40 #retroComputing #epson

Sheet of white paper in a dot matrix printer. On top of the sheet there are multiple lines of very faint text, then two lines of much darker, clearer characters.

Why buy boring white paper when you could have glorious dull pastels reminiscent of the wardrobe choices of Miami Vice? Also, look at that font! Perfect 80s vibes.

My banners are going to look totally rad.

#dotMatrix #retroComputing

Well, internal test works - ribbon is pretty much dead but that was to be expected. Still, it sounds pretty good now. Will try to revive the ribbon.

Warning: might be loud.

Edit: Connected it to my Apple IIe's parallel printer card later on and I was able to print from BASIC. So it works.

Side by side view of my two Epson LX-80 dot matrix printers. The one on the right I got free at #VCFEast really needs a good cleaning before I'll start testing it.

Two identical mid 1980s dot matrix printers, the one on the right being far, far dirtier than the one on the left.

Remember when computing-related books had fun stuff like DIP switch settings?

#retroComputing #Epson #dotMatrix #book

Page from a spiral bound book with the following text.

Always turn the power OFF (with the switch on the right side of the printer) before you change the setting of any of these switches. Any changes made while the power is on will be ignored until you turn the printer off and back on. So set all switches with the power off.

In Table D-1 we show you the functions of all the switches. Then we explain each of them. I zibson A

Switches 1-6, 1-7, and 1-8 determine the active international character set.

Book and card got here, will be plugging in the latter this weekend in my Apple //e and connecting it to my Epson LX-80. I already had a PDF for the manual, but the real spiral bound thing is so much nicer!

Just bought a book from eBay that comes with a weird dongle. Looking forward to reading it, I'm sure it will be exciting.

RIBBONS! A box just arrived of new #Commodore MPS-1250 ribbons & the best part, they were under $3.10 a ribbon. That is a surprise being lately some ribbons are not even available anymore & others are $45+ a ribbon.
