I had my first type of dumpster score, I was delivering to a house and the next door neighbour,asked me could I make use of a printer, I said yes, and made off with the treasure, when I stopped and had a look, it's was a HP laser printer,which I use now for making toner s track schematics for my pcb's definite winner,not only was I given the printer,I was also given 10 of each colour including black cartridges .
