>Do you have cups-filter 1.28.15 installed
Yes, and I rebooted after installing it just to make sure. Problem
persists.
>Or did you try the option "pdftops-renderer=gs" as described there and
which you confirmed as fixing that bug?
I _also_ have this setting in my printers.conf. So clearly this bug is
different from that one.

These two statements seem to be contradictory. If driverless printing is
more reliable, that would seem to imply that files sent directly to the
printer print more reliably than files sent through the CUPS filters,
which would seem to imply that it is the filters, not the printer, that
have bugs.

Title:
File fails to print when rendered with CUPS, prints fine when fed
directly to printer
Status in cups package in Ubuntu:
New
Bug description:
I have a printer named "duplex" configured to print through CUPS
PostScript rendering ("MakeModel HP LaserJet 500 color M551 Postscript
(recommended)", "DeviceURI
socket://m551dn.kamens.brookline.ma.us:9100" in printers.conf) and the
same physical printer configured driverless in CUPS with a different
name ("MakeModel HP LaserJet 500 color M551, driverless, cups-filters
1.28.15", "DeviceURI
implicitclass://HP_LaserJet_500_color_M551_1637DA/", "Option cups-
browsed-dest-printer "1625
ipps://HP%20LaserJet%20500%20color%20M551%20%5B1637DA%5D._ipps._tcp.local/
pdf 600dpi"") in printers.conf.
The attached file prints just fine when sent to the latter printer,
i.e., prints fine with driverless printing, but fails to print when
sent through the CUPS Postscript renderer, i.e., the former printer.
In particular, the file stops printing after four pages and then the
printer spits out this error page:
