I was going to let this go because it takes us beyond the server
situation we are discussing and is a reasonable, succinct description
of classic printing (which will become unsupported by CUPS in a few
years time).
However, modern printers will accept and print jobs (e.g. PDF and JPEG)
without the mangling. These AirPrint-enabled, IPP printers completely
do away with having to use non-free software or plugins also. What is
there to dislike about that?

So - I give my VIP, Android-using customer a piece of paper with a URI
to type into his phone rather than telling him which printer to use to
print out the multimillion Euro contract he has just signed? Very last
century. Anyone fancy carrier pigeons?
