I have for sale an Oki C911 printer. It can print up to SRA3 in size and up to 250gsm paper weight.
It's quite large, very reliable, needs a set of toners and will contribute to your hernia if you don't have muscle (aside from me) to help when you collect it.
Pickup only (read the bit about the hernia) and it's in the Hamilton CBD.
Price - Looking for fair offers - I've not seen one for sale on other sides so can't speculate.
