I have a large graphic (map) that I need to print to specific sections at a time.
Is it possible to lock/move the print area to a specific sections of the graphic, rather than move the entire graphic to fit into the print area?
You may already be aware of this. If so, then please take no offense that I point this out.
If you can use a workflow that uses CorelDRAW's "Print..." dialog, then you have access to a number of options that are not directly covered by Publish to PDF. Those include layout options, tiling, imposition layout, and more besides.
For your particular case - printing a specific area of a drawing that is larger than the target page size - the layout options could be useful. In Print Preview, for example, you can click and drag to interactively select the area that is being mapped to the printed page:
The "printer" could be a physical printer, printing to a file using a particular printer driver, or printing to PDF if you have the full version of Acrobat (or something else that can function as a printer driver and create PDF content).
He could also use the device independent postscript driver then Distill a PDF.
