Printing is our biggest nemesis. We have an full on freestanding office photocopier/printer which we lease, and it's very popular as it does A3, sheet fed scanning etc etc. We pass through the cost of printing with no markup, as our ethic is that people pay their membership fee and that's where we make our money (not a markup on phone calls/printing/snacks etc)
However, we have an ongoing issue with our printer and the newest Mac OS El Capitain (and specifically the account track software which is used to keep track of who is printing how much). The two just don't play nice, and we've got a lot of frustrated members, many of whom now print through our reception PC, which isn't ideal. We've tried to resolve it many times, but have got to the point where we either need to buy another printer to go alongside the main one, or remove the account track system. We're considering the latter- for a space like ours with £20k+ revenue a month, a £100 non markedup spend on printing is not worth upsetting any members.
