Oky lets start from the beginning and i never new this until some research.
I was printing away one time on a laser printer and i saw some thing one time that looked wired. Ar first i thought it was just me until it happened again another time were the light just caught the page just right and i saw some yellow dots.
After a bit of research i found that Most laser printer print on every page the time and date a serial no and some do more info like user (if run though windows) .....
This is so that the document can be tracked back to its original source.
This is no joke after more research ive all so found that they are implementing it (if they haven't already) on all color printers inc ink jets.
You can find out how to see the code on laser printers here ->
Another way of tracing what you are up to ..
do you think this is wrong ... Id like to know that this is on my printer before i buy it personally. I dont mind it being there but full disclosure when buying items like this is a must i think.
what do you think
