Hi RnRMusicMan,
1. I do not have problem with copying.
2. I am using Windows 7.
3. The HP Officejet 6600 is connected by USB - it kept going offline when I connected with wifi.
There is no streaking or other quality issues - it just decides to skip a few words from time to time, and sometimes an entire line. It does the same thing when I tried to print the same document again, skipping the same words. The words in the documents are in black (not color) and I printed in grey scale.
Thank you.
