Hi carmar
unfortunately your suggestions did not work and I lost printing and scanning functionality.
So after removing all printers using synaptic and then lpstat -p and lpadmin -x, I reinstalled using synaptic:
but deleted:
I ensured that printers via the printer manager were all removed.
Once these were reinstalled, I used the printer manager to find and install the networked printer.
This resulted in two semi-identical (this time) printers being installed again, with #2 popping up automatically once #1 was installed.
#1 called Samsung-CLX-3300 driverless;
#2 called Samsung_CLX_3300_Series_SEC001599D21FF6_
This gave me back scanning functionality and semi-printing functionality.
By semi-printing meaning a test page sent to #1 would only print in colour mode, but any changes to print only in monochrome or grey scale would print garbage until it emptied my paper tray. Sending a test page to #2 prints garbage regardless.
Printing only in colour mode would be fine when printing text IF the print came out purely in black and white but it doesn't. For some reason it tries to mimic b&w and the print is more black text with a background trying to be white but comes out hints of greyish or psuedo-grey, something like a scanned text page which is then printed. This results in an unclean print for me.
I tried using Libre writer and default text editor to the same results (thinking maybe it had something to do with how the driver was implemented).
So either the linux drivers available for my printer do not seem to do a great job at printing or the double installation of the printers are again causing conflicts.
I will be doing some trial and error in the next few days and removing and installing printers etc in various combinations to see what happens.
Thank-you again for all the help you have given. Have a great weekend!
