Print to a pdf. Then, calmly, print pages from that pdf, at the rate and quantity you desire and on the printer you want.
I agree with siplus, but unfortunately printing 7000 pages to pdf could be a challenge on its own. Break the job into chunks - at least two parts into two pdfs so you can print on both printers at the same time.
You can also consider sending the output to a print shop.
The script is very long and I do not speak Danish, but for such a big job you might consider to simplify or optimise it
Thanks to the both of you.
Sorry I didn't mention the Danish thingy.
I'll go with the idea of simply Print to a PDF and then print the pages into chunks in our own desire.
Again, thank you for your reply.
If it were me I would save as a PDF or two and send it to a print shop with high speed printers.
