A script could be written to install drivers;
A simple one could have an rpm -i name-of-driver
or a rpm -Uvh name-of-driver
It may be easier to simply run the instal command from within the folder where the drivers are located. i.e. in Dolphin it's just a matter of pressing F4 to split the screen with the top half showing Dolphin and the bottom section showing a Konsole from where the install command can be run.BUT
in saying that, you would need to find out if the downloaded drivers are compatible with PCLinuxOS as they may install okay but could cause issues with other components, and as they are non-repo drivers
forum members may not be able to provide assistance as they wouldn't know the differences from your "local" install and a "repo" install.
Have you searched the repo for your printer? Quite a few are covered. Is task-printer
installed? they are a good place to start.
Lastly, you could do a Requested Package Updates or
a New Package Request
after reading the following links.
I'm unsure whether the Regularly updated packages
covers printers or not, mebbe pinoc
