Canon imagePROGRAF printers are able to print with out the need for Postscript?because Canon?s own GARO (Graphic Arts?Raster Operations) page description language will handle these as a postscript interpreter without?any problems.
Canon iPF printers?are able to print the industry?s most commonly used file formats (PDF,?DWG, TIFF, JPEG, HP GL/2, HP?RTL) from applications such as AutoCAD, Photoshop, Micro?Station, and Microsoft Office without the need for PostScript. For the majority of CAD/CAM/CAE?(2?D AND 3?D) printing, PostScript is not required because Canon?s own GARO (Graphic Arts?Raster Operations) page description language will handle these as a postscript interpreter without?any problems.
The Canon Printer Driver, built around the GARO page description language was designed to?address a broad range of output requirements. Nonetheless, there remain some occasions where?PostScript may be useful ? such as when printing high?end graphic arts applications and?occasionally in a UNIX or LINUX operating environment. If the customer wants to print graphic?arts applications such as Illustrator, Quark, InDesign, CorelDraw or?PageMaker, then they will require a PostScript enabled RIP solutions to address this need.
