5.5. Wildcard Printcap Entry

If you specify a printcap name or alias as * (wildcard), then if the LPRng system cannot find a printcap with the exact name then the first matching wildcard will be used. For example:

    pr|*:rm=server
      lpr -Ppr2 will match, and result in a printcap entry
        pr|pr2:rm=server
    
    *|pr:rm=server
      lpr -Ppr2 will match, and result in a printcap entry
        pr2|pr:rm=server
