Is it Windows 11 or the printer?

[TOPSie]

My applciation prints a report for Invoices - A5 paper, double sided. Some reports have two pages, some have only one.


A batch of invoices are printed at once - the code loops around an OpenReport changing the various fields each time round the loop.

All worked fine then two things changed. The PC was upgraded to Windows11 and a new model of the printer was installed.

Now when a batch of reports is printed, if one Invoice only has one page, then the next invoice is printed on the back of the previous one, rather than leaving the back of the first one blank.

Do I blame WIndows 11 or the printer?

I would say neither.
Try creating a few reports as pdfs, 1 pagers and two pagers. Then print a mixture of those pdfs to printer and see what is produced.

it wouldnt hurt to search for the latest 64bit driver for the printer.
