Are your reports successfully generating in both languages? The printer should be imaging exactly what it “sees”, regardless of language or symbols….perhaps there is something missing on the computer itself, such as software which will convert the language prior to sending the reports to print? You should be able to print from a website in Arabic – I printed off a page from this this site on my laser printer to test this for myself.
However, in printing a Web page, the page is rendered as a Postcript image to the printer
The initial request was for printing individual characters, Ascii values in the range x’80’ thru x’F0′, as the Arabic ‘glyph’ ( character )
