FIX: Invalid or unknown format for print spool file when printing from the Zetafax API



ID: ZTN1736

This Zetafax technical note applies to:

  • Zetafax v2007 and later


When using the Zetafax API printer functions, the Zetafax Client displays a message saying ‘Invalid or unknown format for print spool file ZETAFAX.SPL’


The problem is caused by the way in which some applications remember their print settings, which could cause an unsupported printing resolution to be used.


A hotfix is available. Please contact Equisys technical support for details.
