OSX 10.6.8 Snow Leopard? Wow. (I still have an old G5 running 10.5.8 for my scanner.)
I’ve been using QTR almost as long as it’s been in existence. This thing where it stops printing mid-print has happened to me once in a great while. It’s happened with the Epson driver a few times too. I think it is some sort of communication error. Maybe your USB cable is bad. Or maybe too long?
Are you saying that you are trying to print an 8x10 image on 8.5x11 film? If so, did you read the 1430 instruction pdf? It specifically mentions leaving a 2 inch margin on the bottom edge. It also suggests using 11x17 or 13x19 sheets for the same reason. If you have removed the star-wheels, this printer needs a little extra material in order to feed straight as it nears the end. I found the margin requirements to be 0.5 inch at the top and 1.5 inches at the bottom. Sides can be as close as 1/8" (0.125) or whatever the QTR minimum is. I think that the banding if you try to print too close to the leading edge is a common problem with this particular printer, and the solution is to give it the margin it needs.
Personally, when printing actual images (rather than test targets) I like to use film the same size as the paper I will be printing on because it makes positioning really easy. I sometimes trim the film to size after making the neg.
If you are trying to get by with 8.5x11 film for economy purposes, I would suggest that it is a false economy in that your failures will quickly cost more in materials than using larger sheets. But here are a some possible solutions:
- Reduce the size of the target file (if that is what you are printing) to accommodate the necessary margins.
- Don't forget to expand the canvas size to match the sheet size and fill with black so that the margins remain clear.
- Get 13x19 sheets and cut them in half to 9.5x13.
- Get a 17" roll and cut to the needed size such as 8.5x12. This is what I am doing for test targets since I had a roll on hand.
I hope this is helpful. Sorry if I misinterpreted the issue.
