Max print and file size with print tool on a mac

I have a pretty robust mac pro … 2x3.4 - 12 processors and 64mb’s ram. So the computer handles multi GB files. Right now I use a short 36" very, very high quality usb in the past I used ethernet. The file gets to the printer quicker than my older quad core mac pro with ethernet. I am printing on a 9880.

I have not heard the rotate image in photo-shop worth a try, but the image I am working does not need a rotation.

Printed files are flattened gray scale tif’s. My ideal is to print the image at 16bit, 720dpi at print size so yes I am referring to print size with resolution numbers. Just use standard - 2880, single pass settings for print tool.

The files I am working with are large enough where they can not be saved as a tif - bigger than 4gb. so I have to make a tif to print. I reduce them to the above specs for the file I print. Ideally I would like to be able to print any tiff.

The question I have is whether print tool has a limit on tif size, or print size.

There are lots of ways to reduce a file size, I try various things … i can see a degradation in image quality when I get in the 750 mb range where the printer works fine … files in the plus 1.2 GB range have the quality I want, but I am unable to get a complete image to print. Unfortunately I have enough paper for about 3 or 4 more tries and need 1 print for an exhibition in three weeks. So I can not fool around with this.

Incidentally - When I print the large files in the range of 1.2gb - 1.8gb - at 2880ppi on a small sheet paper/image they often print fine … when I then go to the 40" roll of paper at 720 … I have problems with the prints.

So my first question is - are there limits on print size and or file size built into print tool. And if there are limits what are they. ??

And the second part would be … helpful ideas like you offer here where I might be tripping up the system, especially if I should be able to print the large files.

Hey I know it is Christmas … so I am hoping some folks get bored with football and turkey and look at the forum. I imagine once I get by new years I will be feeling like I have to figure this out. thanks for taking the time to help me out – michael
