21 August 1970
I learned something about computers (or printers rather) from my Dad last night. I was complaining that my printer wouldn't print in black and white if it thought it was out of magenta. His solution? Tape the clear part of the cartridge. I had never thought of that before. The printer must use a light emitting diode to detect transparency in the cartridge. Taping the transparent part makes it appear full. Voila!
I'm sure most of you already knew this, but in case you didn't.
