Check the DocuTech 6180 Knowledge Base as there are two or three solutions for working with LPR. They are not written with Windows 7 in mind since the DocuTech is way before Windows 7, but you might be able to adapt the procedure to get it to work for you. After you click on the Knowledge Base link that I added above, type "LPR" (without the quotes) in the search field and then look through and read the results for the LPR solutions. Hopefully something will work.
I work with Ting and we are trying to set staple option to "1 Staple Landscape Left" using "LPR -C "(staple=singleLandscape)" but "1 Staple Portrait Left" is what's set. Any idea's? I beleive we are on FreeFlow version 6.
We got the setting from Xerox manual listed below.
