Unable to print Word document

Try these.

Check if your system recognises the entire 256MB during booting. Sometimes the SIMM and DIMM cards might be loose.

Also

Increase the swap space and the virtual memory on your HDD.

Leaving aside the possibilty of a corrupted font, search for and rename any Normal.dot files you might have. There should be only one.
Delete any ~*.* files. Word leaves shards wherever documents are stored.
See how many fonts are installed. Around 500 to 650 max is the usual suggestion.

Do you have any graphics in this document? The problem has been reported to occur with TIFF, BMP, and JPEG files. If so this problem has been reported to occur if you have an incorrect or outdated printer driver. To correct this problem, either install the correct printer driver for your printer, or update your current printer driver to the latest driver version. To obtain the latest driver for your printer, contact your printer manufacturer.

Another possible cause: I also had this problem when I tried to fax a 2 page Word document from my computer using the WinFax printer driver. I had a bmp graphic on the second page that went a little past the margins and I had my margins set at .5 for each (top, btm, left and right). When I corrected this and let Word adjust my margins, I was able to fax with no problem. Hope this helps.
