Hi,
I recently had the same question using WordPerfect 10. I was told to print the WP document to a file. It's a long workaround, but it did work for me...others have reported mixed results.
Find out what kind of printer your client will be using to create the printout and install the printer driver for that model on your computer.
Then open the document you want in WordPerfect. Choose File^Print. In the Print dialog box, select the client's printer from the Name drop-down list and check Print To File. Set any other options and click Print. Name the file whatever you want, but save it to a location you can easily find it.
Once the file has been created, email it to your client. Once he or she has saved the file to the hard drive, have the client launch the MS-DOS Prompt (Win98) or the Command Prompt (Win2k) and type
copy filename.prn lpt1
Assuming the printer is on the lpt1 port. Otherwise, have the client enter the path to the networked printer. The file should print properly. If not have the client type
copy /b filename.prn lpt1
(The "/b" switch means "binary copy" DOS may not print the file properly.)
Hope this helps,
Chris
