Specifying printing options in Red Hat Enterprise Linux

Issue

• How to specify options for printing in portrait mode or tray settings in cups on Red Hat Enterprise Linux ?
• How to set printing from CUPS to default to landscape?

• How do I Configure printer configuration with the following options:

  Page Bottom 43
  Page Left 28
  Page Right 28
  Page Top 36
  

• I have added lpoptions using:

  lpoptions -p SPPRTCNTR -o"cpi=17 l=66 page-bottom=0 page-left=25 page-length=66 page-top=0"
  

  Yet when we print reports to this printer, the print comes out of the printer in "10 cpi" and NONE of the features that we set with lpoptions.

• We want to print a cover page, however using the following command doesn't work:

  lpr -P bprinter -o InputSlot=tray1,job-sheets=classified test.txt
  

• How do I set the default to output to tray 3 only via command line.

• How to I change the paper type in CUPS. CUPS will currently only print on A4 paper.
