The subject problem will occur if the document contains a font that does not exist on computer B. Depending on the installed fonts, the GDI font mapper may substitute diiferent fonts for the unknown font on different computers. This may cause text to be larger or small, causing the printed document to expand or shrink relative to the original.
To work around this problem, determine the missing font and create an explicit substitution by editing:
HKEY_LOCAL_MACHINE\ SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes
On the Edit menu, click Add Value and enter the Facename of the unknown font
as a type REG_SZ with a string value of Facename of the substitute font
If your system is mapping Geneva to Helvetica, but Helvetica-Narrow would be a better choice, Add Value
Geneva as a type REG_SZ and set the string to Helvetica-Narrow.
