[Misc] Question on VarioPRINT Print Engine and Controller System Options

[QC91]

Hi, are office is looking at getting VarioPRINT 115, but we got different answers on Print Engine and Controller System Options are office does all PDF Print jobs 400 to 1200 pages each job. one dealer says we need the Streaming-C1 5874B001AA or when it raster image processor RIP the jobs it will not print until all pages have been processed, the other dealer says it does not matter, we need the job to print immediately


right now our office has 2 imageRUNNER ADVANCE 8505i and they print immediately we are looking for the same capability


Any help would be appreciated
