Issue with printing as "Adobe PDF"

Hello all,

I am having an issue in Excel, where I go to "Print" then select "Adobe PDF" and create a PDF version of the printed spreadsheet, I get the following error:

%%[ ProductName: Distiller ]%%

Aptos-Narrow-Bold not found, using Courier.

%%[ Error: invalidfont; OffendingCommand: xshow ]%%

Stack:

[37 44 42 15 38 21 44 0]

(



)

%%[ Flushing: rest of job (to end-of-file) will be ignored ]%%

%%[ Warning: PostScript error. No PDF file produced. ] %%

Anyone know what may cause this issue? For referance, I am using Acrobat Pro. 

Thank you
