When you say print an inch then blank an inch. Does the paper move and the head work and imply leaves blank paper? Or do mean the printer stops a while then picks up from where it left off. Is this a bubble jet?- That is does the cartridge come with the heads built in and a contact strip on the side - Or is it the other sort where the cartridge is an ink tank and the head stays in the machine, but are removable? If you get a completed document but with blanks this is a head problem. If you get a complete full document but the takes breaks this is a computer spooler problem A head problem Take the cartridge and/or head out of machine and stand in a saucers with a tissue damped in a water /alcohol mix -Windex, or car screen wash, even Jack Danials or your favorite spirit. When the tissue is thoroughly discoloured[leave overnight]- replace and give the machine ar un and come back. If it is taking breaks but eventually giving a complete document then check out drivers/Scratch disk and software on the computer.
