I found solution to my problem by doing this: 1-assured that in /etc/papersize there is written only a4. 2-open /usr/share/ghostscript/8.71/lib/ghostpdf.ppd and erase every line with inside the word "letter". 3-open /etc/cups/ppd/KM-1635.ppd (instead of KM-1635 use the name of the printer that doesn't print to a4) and delete the line where there's write letter/letter like this
*PageSize Letter/Letter: "%% FoomaticRIPOptionSetting: PageSize=Letter" *FoomaticRIPOptionSetting PageSize=Letter: "-p1 " *PageRegion Letter/Letter: "%% FoomaticRIPOptionSetting: PageSize=Letter" *ImageableArea Letter/Letter: "12.00 12.00 600.00 780.00" *PaperDimension Letter/Letter: "612 792" 4)changed in firefox at about:config every line where there's letter on na_letter or letter to a4 and the dimension of that format forced to height 297 and width 210. when i restart firefox the values of print.postscript.paper_size was returned to letter for example but the printer print correctly to a4.
