I had two bits of unused hardware knocking around – a Raspberry Pi that used to run my Go Free Range weather printer (the thermal printer broke – another story), and an old Samsung ML-1510 black and white laser printer that was pretty useless to me as you can’t get up-to-date Mac OS X drivers for it. The laser printer only cost me about £40 when new, but I hate seeing things go to waste.
I wondered if it was possible to glue them together – turn the Raspberry Pi into a print server that I could leave on all the time plugged into the laser printer. And, dear reader, it is possible. And incredibly easy. Using this guide: http://www.bartbania.com/index.php/cups-raspberry-printer/ I had it working in about 30 minutes.
