Documents failing to print in RHEL with error "client-error-document-format-not-supported".

Issue

• All configurations were generic text-only printers. I have validated that my server can ping the server host and the print queue name, but when I try a test print, I get the error "There was an error during the CUPS operation: 'client-error-document-format-not-supported'".
• When we define a new generic text-only printer and print a test page, we get "client-error-document-format-not-supported."
