Open the CIPO recordAbstract From the Canadian patent
A continuous-paper electrostatic printer saves paper by avoiding needless feeding of paper to the electrostatic printing section when there is no data to be printed. This is accomplished by providing a paper cutting means downstream of the paper holder of the printer and ensuring that paper is not transported upstream of the cutting means to the printer when there is no data to be printed and by ejecting the section of cut paper from the printer system at the same time .

Why it's free to use
- Filed December 21, 1989 and granted September 24, 1996. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 21, 2009.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 21, 2011.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
