You asked for it, and Clem delivers! After he built the Phone to Printer Port adapter, a lot of viewers were asking if it was possible to add Wi-Fi to this old dot-matrix printer. Clem takes on the challenge, and walks you through the troubleshooting and solution finding to add Wi-Fi to any old printer!

    Not so subtle… okay I’ll build one.

    Hmmm… Challenge accepted! Shouldn’t be that hard to implement since it exists since the dawn of the computer… er… almost… 1990. I would give it a shot if only I could get my hands on a prototype

    that must be have been the biggest headache relief since the invention of aspirin.

    I had a project that needed to use an old ASR33 teletype for code entry. It would take up to an hour to load my paper tapes.

    When the project ended, one of the guys in the room came up and gave me a big hug to show his appreciation for the silence.

    It's okay. I'll make my own. I'm sure someone else could benefit from your generous offer though. :-)

    thanks DAB
    I'm actually a noisy printer enthusiast, so If any I would try to make it even more pronounced. for the longest time I had a 3,5" floppy drive in my modern pC just for the sound on boot. maybe this printer will serve a similarly pointless purpose.

    Good job Clem.

    Maybe next time you can take on the challenge to make the printer quieter while it runs.

    You can certainly give it a go!
    Send me a DM with your adress , I have a spare PCB here that I could send to you. (you'd need to source the parts yourself though)

    Hi Clem, why not implement RFC 1179? You wouldn’t need special software if this was an lpr network printer.
