Print a large file, in parts?

Question

Printers

There is a device Sharp MX-M1100.
It prints a huge number of stapled copies.
Example.
1. Document 1 - 50 stapled copies required.
2. Document 2 - 50 stapled copies required.
3. Document 3 - 50 stapled copies required.
It turns out 3 packs, 50 copies each, then it must be decomposed.
Document 1 + Document 2 + Document 3 = 1 set and so 50 sets.
In general, everything is printed in large volumes and sorted by hand (stupid routine)
I wondered:
- if you glue Document 1 + Document 2 + Document 3 (originals) into one pdf document;
- make a split page inside the pdf, a blank page for example;
- i.e. will go Document 1 - white page - Document 2 - white page, etc.) get a large file, pp. 200-300;
- roughly speaking, you will get a huge pile of copies, but they will all go Document 1 + Document 2 + Document 3, 123, 123, etc.
- let the printer know where it will stop, stitch, continue printing.
Tell me / Throw ideas (maybe someone sawed something like that) how can this be washed down so that the printer understands where to divide? Maybe there is some software for this. There is nothing useful in the printer settings.
Any information would be helpful.

Answer 1

A non-trivial task, certain programming skills are needed to implement it.
Most likely, the enlarged statement of the problem will look like this:
In any programming environment, we write an application that sends commands to the Windows command line according to the following algorithm:
1. cmd command to open Document 1;
2. cmd command to open Document 2;
3. cmd command to open Document 3;
4. Cycle through the pages of document 1;
4.1. Upon completion of the previous macro, run the macro to print the i-page of document 1;
4.2. Upon completion of the previous macro, run the macro to print the i-page of document 2;
4.3. Upon completion of the previous macro, run the macro to print the i-page of document 3;
5. cmd-command to close Document 1;
6. cmd-command to close Document 2;
7. cmd-command to close Document 3;
It seems that the algorithm is simple, but at each step you need to catch exceptions and it is possible to control the process of starting the stop from the application.
