Well, I also got your problem. ~~>_<~~ As different printer, the print
margin is different. I got alright on printing label to fit the Label paper
first row... but half cut on 1st row on client Printer....

For blanking the 150 frx file printer info.
try this coding:

nFileCount = ADIR(frxFile,"*.frx")

 IF nFileCount = 0
    MessageBox("No .Frx File is found at "+CURDIR(),0+32,"What a Pity!")
    RETURN .F. && Why .f. - on purpose ?
 ENDIF

 for iCount = 1 to nFileCount
     use frxFile[iCount,1]   && Dirinfo is two dimensional
     blank fields expr, tag, tag2         && Blank to remove printer driver info
     Wait "Cleaning "+ frxFile[iCount,1] Window NoWait

     if "PLAN" $ frxFile[iCount,1]	
* Plan.frx need Orientation=1 means Print in Landscape
* You can add any if you sure the report is in Landscape!!
     	replace expr with "ORIENTATION=1"
     endif

*     tableupdate(.f.)		&& Force to Flush as I use wrong buffer mode!
     use  && As Barbara pointed out always the first record
 ENDFOR

 MessageBox("All Bomber .Frx File(s) in "+CURDIR()+" have been Fixed!!",;
                 0+32,"Have A Nice Day!")

^_^; I think I need to post this coding in FAQ!
But first ask Cetin as he did this coding first... (Copy Right ma) =)
