"Pages per side" option buggy for Generic PostScript Printer Foomatic/Postscript

[SimSQ]

I was creating a custom printer backend and needed a generic Postscript output driver. I used Generic Postscript Printer Foomatic, but that gave me problems when I tried to print 2 pages per side.

Actions:
1. For any printer, choose the Generic Postscript Printer Foomatic driver
2. Print to the printer, with "pages per side" option set to 2.

Expected Results:
2 pages per side.

Actual Results:
4 pages per side.

This is a CUPS backend that sends print output to /tmp. It is derived from sshlpr at http://www.masella.name/technical/sshlpr.html

It can be used to test this bug.

Steps to take:
1. Save to /usr/lib/cups/backend
2. chmod a+x /usr/lib/cups/backend/test
3. Create a new printer. Set the URI to test://anything/you/like/there
4. Choose the "Generic Postscript Printer Foomatic/Postscript (recommended)" driver

5. Print some documents, with "Pages per side" option set to 2.

6. View the file created in /tmp
