position with print-scaling does not work expectedly

[xiaowen581]

Describe the bug
when printing with [-o "print-scaling=none position=top-left"], the result I expected was that the picture would be printed in the top left corner, but it was actually printed in the middle.

To Reproduce
Steps to reproduce the behavior:

1. add printer by: lpadmin -p brother -m everywhere -v ipp://[IPADDR]/ipp/print -E
2. printing by: lp -d brother /path/to/demo.jpeg -o "print-scaling=none position=top-left"
   

Expected behavior
the result I expected was that the picture would be printed in the top left corner.

Screenshots
"print-scaling=none + position=bottom-right/top-left" works unexpectedly.

"print-scaling=fit + position=bottom-right/top-left" works expectedly.

System Information:

• OS: Ubuntu
• Version cups_filter: 1.28.17
