Now that more and more reprographers can process DWF files, the most natural way to supply commercial reprographers with files to print is DWF. Some customers have legacy reprographers running old software or old equipment that only understands HPGL. Several Autodesk Revit users have tried sending HPGL to these out-of-date reprographers by using the “capture to file” option of the Revit Print command. Unfortunately there are many flavors of HPGL generated from many different Windows HPGL drivers. We are seeing situations where reprographers aren't able to print every flavor of HPGL correctly. For example, using an HP755 driver with Autodesk Revit to create HPGL files that will be printed on an Océ TDS800 device via Océ Repro Desk has produced undesirable results. So your best option is to use DWF and either help your reprographer modernize his process to support DWF or select another reprographer who can. See my blog post for a list of partner products that can help your reprographer run the right DWF-compatible tools (some are even at no cost to your reprographer). Also we've found that the majority of US Reprographics Network members or ReproMAX members can print your DWF files efficiently, accurately, and at no extra charge.
