In RHEL, printing files named with dots (".") get changed to underscores ("_") when sent to a printer via LPD

Issue

• The print file name is being changed, whereever there is a "." it changes it to a "_".
• When printing to an LPD (Line Printer Daemon) printer, underscores ("_") appear unexpectedly in the title.
• Hyphens (-) are getting replaced with underscores (_) in the printer job name on the CUPS server before the job is sent it to the destination via LPD.
• The '=' character in the banner page job title is being converted to '_' character.

• For example, using the command to send a document to a the XEROX1 print server is:

  lp -d XEROX1 prt7.d
  

  Once received by the print server, the file name is changed to prt7_d. Please help us determine how to keep the dots in the file name.

• We're running a command like:

  lpr -P PRN002 -J identifier=IPRAS026 print
  

  but the equals sign (=) is being translated into to an underscore (_).
