generic-printer-buffer calls lpr-region with incorrect argument

This bug report will be sent to the XEmacs Development Team, not to your local site managers!! Please write in English, because the XEmacs maintainers do not have translators to read other languages for them. In XEmacs 21.2 (beta36) "Notus" [Lucid] (sparc-sun-solaris2.6, Mule) of Thu Oct 12 2000 on ebola configured using `configure --prefix=/pkg/gnu --dynamic --with-gcc '--cflags=-O3 -mv8 -mtune=ultrasparc' --with-x --with-xpm --x-includes=/usr/openwin/include '--site-includes=/usr/dt/include /pkg/X11/include /pkg/local/include /pkg/local/include/db' --x-libraries=/usr/openwin/lib '--site-libraries=/usr/dt/lib /pkg/X11/lib /pkg/local/lib' --with-sound=native,noesd,nonas --with-database=berkdb,dbm --with-png --with-jpeg --infopath=/pkg/gnu/info:/pkg/local/info:/pkg/tetex/info --with-tooltalk=yes --with-cde=no --package-path=/pkg/gnu/lib/xemacs/packages --with-mule=yes --debug=no --error-checking=none' Please describe exactly what actions triggered the bug and the precise symptoms of the bug: Clicking on File->Print "buffer" from the menubar results in a run-time error about lpr-region being called with the wrong number of arguments. lisp/printer.el calls lpr-buffer with "buf" instead of "b e". Either printer.el is wrong or os-utils/lpr.el from the packages has become incompatible.
