My print out defaulted to the colour printer. Over charging and causing a nuisance
The colour printer was the default printer at the time you sent your printing through. The dialogue box that pops up for you to confirm or change the print options would give you the opportunity to change this.
A new print system is coming into the LRCs for 2009 and that will give you the opportunity to cancel any print job - at the last minute if necessary - to avoid mistakes like this in the future.
Please read the pop ups and this should help too.
