Having a problem with our check signature font not displaying in the xmlp check in Payables 9.2

We are in the process of upgrading from Peoplesoft financials 9.0 to 9.2, we are converting from crystal reports check to xmlp checks in Payables 9.2. We seem to be having a problem with our check signature font not displaying in the check pdf that is generated. We have the check signature font installed on the process scheduler machine in c:\windows\font\. If I open the rtf template on that machine, I can see the signature font display, but when generating the check via the app engine process (currently just generating the pdf) no signature is displayed. Has anyone run across
