every update of cups 1.1.18 (suse 8.2) to .19 or .21 results in disabled

[ekkard gerlach]

A update of cups 1.1.18 (suse 8.2) to .19 or .21 results in disabled 
printers. After reboot all printers are enabled. After few hours one 
printer queue after the other is disables and the queue are not to 
enable, neither with web-fronted  localhost:631  nor with lpadmin -p 
<printer-name> -E.

[...]
switch_buero_raw:
         printer is on device 'lpd' speed -1
         queuing is enabled
         printing is enabled
         no entries
         daemon present
switch_zimmer1:

         queuing is enabled
         printing is disabled   <<<<<<======= !!!!!!

switch_zimmer2:

Both tools seem to work. /var/spool/cups/error.log while trying to enable:

I updated my cups1.1.18 of Suse by replacing

cups-libs-1.1.22-2
cups-drivers-stp-1.1.18-34
cups-drivers-1.1.18-34
cups-client-1.1.22-2
cups-devel-1.1.22-2
cups-1.1.22-2


by doing: rpm -Uhv --force --nodeps --replacefile cups*1.1.19*
cups-1.1.19-48.i586.rpm
cups-client-1.1.19-48.i586.rpm
cups-devel-1.1.19-48.i586.rpm
cups-libs-1.1.19-48.i586.rpm
(the rpm's are the files of 
ftp://ftp.suse.com/pub/people/kssingvo/unsupported/CUPS/8.2/RPMS/)


BTW: i don't find the drivers of 1.1.19, where are they?

After restarting cups I have the problems mentioned above.

Any help will be appreciated,

thx
Ekkard, kernel 2.4.26, suse 8.2, some printers (not all)
are connected with a Switch with parallel printer port.
