We had customers that would buy 3rd party ribbons that where practically dripping with ink that would gum up everything in the machine.
Speaking of ribbons, in college I occasionally used a type of ribbon I've never seen on line printers since: a film ribbon. Think of the "letter quality" ribbons used on professional typewriters, or daisy wheel printers, a thin plastic film with some carbon-like coating on one side. Now make one the width of a line printer ribbon.
Our 360/44 normally used a regular cloth ribbon, but a film ribbon could be mounted if desired. I did so to print my honor's thesis, using the film ribbon and the upper/lower case print train (TN train?) to print the final text (from RUNOFF on our PDP-11 system, which had no line printer).
