Not a 2.5.1 error but it may not have been fixed in 2.5.1 as far as admintool....
When trying to add a printer in Solaris[TM] 2.5 Operating Environment
using the lpadmin command, we get the following error;
UX:lpadmin: ERROR: Printer type "hplaser" is not in the
Terminfo database.
TO FIX: Check the name again; if it is correct
you have to make an entry for it in the
Terminfo database.
Or when trying to add a printer through admintool, we get "add printer
failed".
Resolution Top
The problem is that the package SUNWter was not loaded. This package contains
the terminfo database. This package does not install with the core and end user
distributions of the OS. To fix this do the following.
