The is very helpful info for us to help diagnose issues.

I had a look at the specs of the printer and the RIP software:

The RIP software is an older version of Production Manager. Produced, 
I am guessing around 2001. The most current version of this RIP is 
7.6v1 released, released in  March 2005. 

The change log of the software, which is admirably detailed for a 
proprietary app, lists CSPI errors which are fixed in later versions, 
along with notes that Acrobat 5 (PDF 1.4 which supports transparency)  
support was added in a later version. One other line from the change 

*TIFF files with an alpha channel can now import. V 7.5v3

EPS will likely not support transparency directly, but via clipping 
paths will, depending on the contents and how you are displaying

Based on what I can see it is not anything Scribus is doing wrong, 
simply that the older RIP cannot support PDF 1.4 properly. 

You might try using the flattener in Acro 6 or newer, but this still 
might not fix the issue.

Unfortunately, for printers, upgrading RIPs is an expensive and can be 
time consuming job. However, in my opinion, it is well past due.

You welcome to contact me off list to inspect the file too.

Hope that helps,
