Nothing intentionally done for printing an entire job. OE81D allow printing specs to File (instead of printer or screen), with each document created individually and named based on the company profile coding option. But if you are printing to Printer and simply changing the driver to a PDF printer, there was no attempt to change this behaviour.

Do you print using the 'Selected specification' or the 'Customer specification' option? What other options do you use when printing invoices?
