Can't set margins in texttopdf 2.0.0?

[Strahinja]

Describe the bug
texttopdf from cups-filters 2.0.0 (version used in the OpenBSD package cups-filters) doesn't seem to respect the page-* option(s).

To Reproduce
Steps to reproduce the behavior:

/usr/local/libexec/cups/filter/texttopdf 1 user title 1 'media=A4 page-left=56' \
/etc/passwd > p.pdf

/usr/local/libexec/cups/filter/texttopdf 1 user title 1 'media=A4' /etc/passwd > p2.pdf

3. Open both files: p.pdf, and p2.pdf in a PDF viewer.
4. See error - left margin is the same in both files.

Expected behavior
Left margin should be increased to about 2cm in the file p.pdf (generated with the option page-left=56).

Screenshots

System Information:

• OS: OpenBSD-release 7.4
• cups-filters version 2.0.0

Additional context
For example, Alpine Linux has cups-filters 1.28.17 fixed as the last upstream release they use for building the cups-filters package. With that version of cups-filters, the command

/usr/lib/cups/filter/texttopdf 1 user title 1 'page-left=56' /etc/passwd > p.pdf

produces a PDF file with the left margin set to about 2cm. A similar command in OpenBSD:

/usr/local/libexec/cups/filter/texttopdf 1 user title 1 'page-left=56' /etc/passwd > p.pdf

complains:

DEBUG: Color space requested: Default
DEBUG: Final output format: CUPS Raster
WARN: Could not determine the output page dimensions, falling back to US Letter format
WARN: cfFilterPDFToPDF: Could not determine the width of the left margin, falling back to 18 pt/6.35 mm
WARN: cfFilterPDFToPDF: Could not determine the width of the bottom margin, falling back to 36 pt/12.7 mm
WARN: cfFilterPDFToPDF: Could not determine the width of the right margin, falling back to 18 pt/6.35 mm
WARN: cfFilterPDFToPDF: Could not determine the width of the top margin, falling back to 36 pt/12.7 mm

when given the additional parameter of media=A4 (A has to be uppercase, unlike with 1.28.17!):

/usr/local/libexec/cups/filter/texttopdf 1 user title 1 'media=A4 page-left=56' \
/etc/passwd > p.pdf

the output is reduced to

DEBUG: Color space requested: Default
DEBUG: Final output format: CUPS Raster

and there is no difference in the generated PDF from

/usr/local/libexec/cups/filter/texttopdf 1 user title 1 'media=A4' /etc/passwd > p2.pdf

Please attach the ppd file which should be available in /etc/cups/ppd

Please attach the ppd file which should be available in /etc/cups/ppd

With these packages installed:

$ pkg_info -A | grep cups

on OpenBSD-release 7.4 I have:

$ ls -l /etc/cups/ppd/
total 0
$ ls -ld /etc/cups/ppd/
drwxr-xr-x  2 root  _cups  512 Mar 22 17:06 /etc/cups/ppd//
$

FYI, this doesn't seem to be system-related. I have tried the example from the OP in up-to-date Artix Linux (having the latest CUPS), with the same results as in OpenBSD: page-left has no effect, I get the same warnings and the directory /etc/cups/ppd is empty.

In previous versions of CUPS, the texttopdf filter worked without setting up a printer. Still, to test if this is related to adding a printer, I added a "Generic CUPS-PDF Printer (w/ options)" as "Virtual_PDF_Printer", changed its default paper size to A4 and set it up as "server default" in the cups web interface. This created the file /etc/cups/ppd/Virtual_PDF_Printer.ppd (zipped here, as Github doesn't accept .ppd files: Virtual_PDF_Printer.zip). With that, I have (I wrapped the output for readability):

$ doas rcctl start cupsd

However, this didn't change anything - the resulting PDF file p2.pdf still doesn't have the desired margin.
