Well i printed out some encoder disks today to test and did the camera and tv remote IR test as before same problem these HP's are all the same by the looks of it ...
Thats nice cheap laser printer ! yes i give up on the ink ones...that price i will look into it .You will never regret it. After all it's the cost of 2 replacement ink cartridges (and who the hell needs colour anyway?) .
We just need it for invoicing so B/w yes is fine .i didnt buy this latest one the family have a mind of there own so think beyond NBTV uses(how dare they) !
the last one broke and they just went out and got another before i knew about it.BTW I am now in possession of the same printer as your broken one and want to do some experiments on it (seeing is believing) - alas I have become bogged down in house/property projects - darn!

Yes thats a good idea but i am still keeping my eye out on that 40 dollar printer either way my next IR encoder will be either one of those ideas .With regard to the number of pulses per revolution, in principle any number will work providing the 2 sources match - however the more pulses per revolution you have the more accurate it will be.
