Looking for a used wifi printer (mandatory to be working without need of a computer).
Type - Ink Tank or Laser. Multi or single function either is fine.
Note: this is for home usage and not commercial. My existing printer Canon LBP 2900b has served well but requiring a Laptop/system to print has become too cumbersome. Size shouldn’t be very big.
Send in your offers on PM.
Location - Mumbai/Thane preferred.
assuming LBP 2900b still works - you could attach it to Raspberry Pi or cheap HP tiny pcs (costs between 2-4k), install DietPi or something similar + CUPS and you’re good to print it wirelessly.
Since these devices (RPi or HP tiny PC) takes less space and consumes less than 10W or 15w in worst case; you don’t have to worry about the energy usage and if you’re keen - one could install other software’s on top of them and make the energy usage and cost of these devices justified.
I have a Epson L3150 wifi printer shipping from Anupuram - 603127 pincode. I have the outer box also.
