Question about priting 20 pages each page gets printed twice instead of 20 and again 20

[suzana.drenaj]

Question,

When printing 20 pages of a document and selecting to print 2 times 20 pages each page gets printed twice instead of finishing 20 pages and then again printing 20 pages of the same document.

What did i do wrong?

The computer is a windows 10 machine printing on a Ricoh Aficio MP7001

Thank you
