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

Solution Verified - Updated -

Issue

  • The print file name is being changed, whereever there is a "." it changes it to a "_".
  • When printing to an LPD printer, underscores ("_") appear unexpectedly in the title.
  • 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 (_).

  • The '=' character in the banner page job title is being converted to '_' character.

Environment

  • Red Hat Enterprise Linux
  • Common Unix Printing System
