one of the Posibilites is this:
install the Linotronic 230v52.3 printer:
then press "Ctrl+P" for print, and go to properties of the printer, and then advanced:
select print quality: 1693dpi
and script option: EPS post script
and then Ok;
remember to tickmak the check box of " Print to file";
then when you press Ok, it will ask you the location for saving your .prn file, so you may select desktop etc..
then go to corel draw, and import it.
* the imported file is not editable more.
* you can find the Linotronic 230v52.3 printer in Win Xp, so you need only share that printer after installing it in XP O.S, and then go to the XP pc by your Win 7 PC and double click on the Shared Printer, it will ask you to install.
Note: the Second method is to install the WintoPdf converter. Corel Draw accespts this kind of Pdf. even you can convert your other PDFs which are not supported by the Corel Draw by this printer.
