# https://github.com/apple/cups/issues/5269

# CUPS plans to drop '-o raw' support. raw 9100 is the *only* useful
# way to print for a large swath of industrial printers, Zebra label
# printers in particular for which the ZPL and EPL print software will never
# be rewritten to output a CUPS compatible format.
# CUPS is needed for a large swath of WinPrinters
# and for automatic printing of PCL, PXL, PostScript and PDF. Neither
# raw nor CUPS is going away so I fixed lprng to coexist with CUPS.

# Gentoo solves this with a use flag that leaves out the lpr binaries from the cups package
# https://packages.gentoo.org/useflags/lprng-compat
# Debian/Ubuntu solves this with the conflicting binaries in a separate cups-bsd package.

# printcap is also a lot easier to manage than CUPS. Text FTW!

# As of Dec 2018 CUPS raw can be considered as already gone.
# CUPS has two show stopper raw bugs that probably won't be fixed.

# Bug 1:
# https://github.com/apple/cups/issues/4782
# Bug reappeared yet again
#   lp -d lp -o raw file1 file2
# 2 files queued, file1 prints, file2 does not

# Bug 2:
# Some instances of piping stdin '|lp -o raw' or '|lpr -o raw' crash with
#   lp:  Error - unable to queue from stdin - Success.
#   lpr: Error - unable to queue from stdin - Broken pipe.
# lp and lpr are breaking the pipe, not the source. Capturing
# stdin to a file and printing with 'lpr -r -o raw file' works.

# This might be a not yet found bug from glib 2.28 breaking filters.
# https://bugs.archlinux.org/task/60044
# https://github.com/OpenPrinting/cups-filters/issues/58
# https://github.com/apple/cups/issues/5396

# cups-lpr cups-lpd also has some faults

# CUPS printers must be shared to be accessed by the locally running cups-lpr.
# CUPS sharing pollutes the network with unwanted printers.

# -o raw does not work with cups-lpd. It can be tricked into working but
# eventually it will not work.
