Printing with Acrobat from command line

Acrobat Pro: Any ideas on how to print from the command line, suppressing the print dialogue box but still maintaining a high quality print?
 
We are a small printing company using Canon print/copiers to output full color flyers. We print from Acrobat 9 Professional using "High Quality Print" preset. It has recently become necessary, for the sake of time, to automate the print process by using the command line to open, print, and close a series of PDFs, all while suppressing the print dialogue box (there are thousands of PDFs printed on a given day). However, when using the following command (as found in the Adobe Live Docs SDK FAQ), we find that if the print dialogue box is suppressed, the print quality is dramatically reduced:
 
AcroRd32.exe /t path "printername" "drivername" "portname"
 
If we use the "/p" command in place of the "/t", however, and the dialogue box is not suppressed, then it prints perfectly. I am having trouble finding why and where the "/t" gets its print settings, and why the quality is so different between the two.
 
I am not a developer by any means, and am totally at a loss on how to approach this problem. Any insight to how to get a PDF to print from the command line without having to open and click within a dialogue box and without a loss of print quality would be much, much appreciated.
