before i purchased win7, i made sure that my peripherals would connect and run okay. i discovered that my HP5150 printer needed drivers but that they were included on the CD...supposedly. brought my new computer home and tested things out. found out that the cuplexing feature doesn't work like it should. eg. i selected to print a 6pg document. i clicked all the correct settings. my printer printed pgs 1,3, and 5. then the pop box guided me to take pages out of printer and re insert them in opposite direction. that was fine. except there was page in the printer half printed and just sitting there preventing me from inserting my pages to be printed on others side. i discovered that this half printed page was actually half of pg 2...that had already started printing. something is not working here. it used to work just fine when i used XP. can anyone help me out here. i have seen where one can download win7 drivers for HP5150, but am hesitant to do so as i don't want to interfere with the update drivers that we supposed to be on the cd setup of win7.
