Junk values after Converting a document to PDF in Adobe


While converting Word Documents to Adobe PDF, sometimes we observe the below error message.
%%[ ProductName: Distiller ]%%
Cambria not found, using Courier.
%%[Page: 1]%%
%%[ Error: invalidfont; OffendingCommand: xshow; ErrorInfo: CharOffsets         82 30 44 29 59 52
%%[ Flushing: rest of job (to end-of-file) will be ignored ]%%
%%[ Warning: PostScript error. No PDF file produced. ] %%


This error can be resolved by changing one of the Adobe PDF printer settings.  

  • When you are in the print dialog, and you have selected the appropriate PDF printer, select "Properties."  
  • In the dialog box, there should be a tab titled "Adobe PDF Settings," and it should look like the below image.


  • Un-check "Rely on system fonts only; do not use document fonts."  
  • This solves the issue for documents created using XP or Vista, then upgraded to Windows 7.  The Cambria font somehow gets changed between XP/Vista and Win7.

Install and Configure postfix

Postfix is the Linux Mail Transfer Agent that is being used very widely in recent days because of the features that it offers. Installation of Postfix is pretty simple in Debian based OS and a bit tricky in Redhat based. The following tutorial will show you the installation of Postfix in Ubunt and Redhat(in the next tutorial).

Before proceeding we need to make sure that the default MTA sendmail(if installed) should be removed. This can be done by executing the following commands

Debian or Ubuntu :

apt-get purge sendmail

Redhat :

yum remove sendmail

Now we can proceed with the installation of Postfix MTA by executing the following command as a root or a sudo user.

apt-get install postfix
apt-get install mailutils

Normally in Debian based or in Ubuntu operating systems once after the installation a wizard is started to complete the configuration of the Postfix, follow the below steps to complete the general postfix configuration










once the configuration is Done, restart the postfix service for the changes to take effect.

service   postfix   restart
