manually adding 'cups' solves the issue -- a "Requires: cups" seems in order, or
a virtual "Requires: print-server", and configuring cups to 'Provides:
print-server' if one wants backward support path for lpr. lpr-ng, and so forth
Comment 1 Tim Waugh 2003-10-13 04:49:22 EDT
No, this should work fine with LPRng.  What does '/usr/sbin/alternatives
--display print' say?
Comment 2 Miloslav Trmac 2003-10-13 06:42:51 EDT
This is a duplicate of bug 85363. 
Comment 3 R P Herrold 2003-10-13 09:04:55 EDT
Recall that I manually added 'cups' to get it working:  After that, it says:

[herrold@ftp herrold]$ /usr/sbin/alternatives --display print
print - status is auto.
 link currently points to /usr/bin/lpr.cups
/usr/bin/lpr.cups - priority 40
 slave print-lp: /usr/bin/lp.cups
 slave print-lpq: /usr/bin/lpq.cups
 slave print-lprm: /usr/bin/lprm.cups
 slave print-lpstat: /usr/bin/lpstat.cups
 slave print-cancel: /usr/bin/cancel.cups
 slave print-lpc: /usr/sbin/lpc.cups
 slave print-cancelman: /usr/share/man/man1/cancel-cups.1.gz
 slave print-lpman: /usr/share/man/man1/lp-cups.1.gz
 slave print-lpcman: /usr/share/man/man8/lpc-cups.8.gz
 slave print-lpqman: /usr/share/man/man1/lpq-cups.1.gz
 slave print-lprman: /usr/share/man/man1/lpr-cups.1.gz
 slave print-lprmman: /usr/share/man/man1/lprm-cups.1.gz
 slave print-lpstatman: /usr/share/man/man1/lpstat-cups.1.gz
Current `best' version is /usr/bin/lpr.cups.
[herrold@ftp herrold]$

And redhat-config-printer is not interlocked from breaking printing again.  It
should have complained with the following, but it did not:

[herrold@ftp herrold]$ sudo rpm -e cups
warning: /etc/cups/printers.conf saved as /etc/cups/printers.conf.rpmsave
warning: /etc/cups/cupsd.conf saved as /etc/cups/cupsd.conf.rpmsave
[herrold@ftp herrold]$ /usr/sbin/alternatives --display print
[herrold@ftp herrold]$

so it appears an explicit dependency, possibly on a pseudo meta-package, is

BTW -- this host was a "kickstart" 'from scratch' new build, after a hard drive
died last week.  
Comment 4 R P Herrold 2003-10-13 09:06:47 EDT
chuckle:   I just read Miloslav's dupe, referenced, and Tim's comment there was:

""------- Additional Comment #3 From Tim Waugh on 2003-08-08 04:04 -------

redhat-config-printer should require cups.""

Comment 5 Tim Waugh 2003-10-13 09:21:43 EDT
Oh, not a standard install.  Well, yes, you need to install a print spooler for
redhat-config-printer to work.

LPRng is not shipped any more, so the requirement is already there in rawhide --
but there is no plan to add a meta-requirement for existing releases.
