When Citrix doesn’t map the printers via the portal you have a couple of solution.

I resolved the issue by doing the following steps:

1- Stopping the Spooler service (and it’s dependency)
2- In the registry:
HKLM\System\CurrentControlSet\Control\Print\Printers
I deleted all the Client Printers that were stucked there since the update.
4- Restarted the Spooler (and it’s dependency)

Since this, no more 0×70A error in the Event Log and the Client Printers are correctly created at logon and deleted at logoff.
