This is not needed, pdftoippprinter leads with Poppler-only (and also
Ghostscript-only) systems independent of default configuration. It
always checks presence of Poppler components (/usr/bin/pdftops,
pdftoraster, CUPS_POPPLER_PDFTOPS) and of Ghostscript components (gs,
gstoraster, gstopxl, CUPS_GHOSTSCRIPT) before using them. It also adds
"pdftops-renderer=..." to the filter command line if the absense of a
renderer requires the use of the other, overriding any default settings.
So a Poppler-only system (typical situation for a phone) will work
perfectly, independent of the --with-pdftops=... default choice done at
build time (so we use the most desktop-friendly "hybrid" here).
So do not add Depends/Recommends or use OR ("|") relationships which get
fulfilled also if the system is Poppler-only or Ghostscript-only.
