Cannot print double-sided or landscape to a text-only print queue in RHEL

Issue

• The test of the double-sided page was sent to p12, and it was done in 2 sheets, instead of double-sided.
• I have the lpoption landscape=true set but it is ignored by the printer queue. We expect to see printouts to this queue in landscape mode. We are using the textonly type of printing.
• We want to change the cpi to 15 or 16 on our text only laser printer. We have the following in our lpoptions file: "Dest ITlaser1 columns=132 cpi=16.66 lpi=6 wrap=false" but that doesn't seem to be working.
