Describe the bug
CUPS passes incorrect dimensions to driver when custom media is specified (foomatic driver).

To Reproduce
Steps to reproduce the behavior:

Install printer-driver-ptouch.
Connect continuous tape printer (e.g. Brother PT-D600 [driver not currently included]).

Generate an image via ImageMagick or similar:

magick -size 300x60 -fill black label:"I am Groot" -rotate 90 tmp.png

Print image with specific non-page size dimensions as described by https://www.cups.org/doc/options.html and lpoptions output:
```
lp -d <name of printer> -o media=Custom.6x30mm tmp.png
```
Print fails with message "Page width (448mm) exceeds 255mm)".

Expected behavior
File is printed at specified dimensions.

Screenshots
If applicable, add screenshots to help explain your problem.

System Information:

OS and its version: Fedora 41
Application: lp
CUPS version: 2.4.11

Additional context

Reviewing the printer in CUPS' web UI shows a default media of custom_6x100.19mm_6x100.19mm, but printing with media specified as custom_6x30mm_6x30mm prints at the default page size instead.
