The Citrix universal printer driver (UPD) can generate big spool files. Printing within the LAN and big print data is not dramatic, but over WAN connection the print data can become a massive issue. Quite often printouts from Adobe documents but also other files like Word etc. can become very big.

How does it come to such big print data and how to avoid it? If you know about it, then you can reduce the size by 99%!

After implementing Citrix Universal Print Server (UPS), you might run quickly into error message "0x00000709", when printing. The reason for that is that Printer vendor set their printer to RawOnly, even the printer can work with different format like EMF. Citrix UPS uses EMF only and the source of the error message.

I had several incidents now with customers and the Citrix universal print server (UPS) that I like to share with you. Many complain that UPS is not working are based on missing information not published by Citrix.

Slow logons are already an issue but when it gets to a certain duration then it causes massive problems when using only publish application. Things can get even worse when Citrix user profile manager automatic configuration has not been disabled. Automatic configuration of UPM enforces profile streaming and it might and can cause further issues when dealing with a lot of small files like ini files, cookies, bookmarks and others.

Upgrading the Citrix Virtual Delivery Agent (VDA) seems to be more and more a problem than an easy process. I don't understand it anyway why the VDA cannot be pushed by the DDC on request. Meanwhile, we have to fight Citrix and Microsoft to get the VDA installed or upgraded. Here are points you should follow to be successful.
