When you try to create a new 3270 print session or an APPC print session on a Microsoft Host Integration Server 2004 Service Pack 1 (SP1)-based server by using the SNACFG (snacfg.exe) command-line configuration utility, you receive the following error messages:
Undefined parameter FONT
Undefined parameter FONTSIZE
Required parameter missing or parameter value invalid
Note This problem can also occur on a Host Integration Server 2004 server that has the following update applied.
937144 FIX: You cannot use the SNACFG utility to configure the “Use fixed font size” option for 3270 print sessions and for APPC print sessions in Host Integration Server 2004
This problem occurs because the SNACFG command-line configuration utility incorrectly checks for the existence of the /FONT parameter even though the /OVERRIDEFONTSIZE=No parameter is specified in the command to add a 3270 print session or an APPC print session. The /FONT parameter and the /FONTSIZE parameters only need to be validated when the /OVERRIDEFONTSIZE=Yes parameter is included on the command to add a 3270 print session or an APPC print session.

You can configure the "Use fixed font size" option for print sessions by using the /OVERRIDEFONTSIZE parameter. The sample SNACFG commands in this section show how to do this for an existing 3270 print session. For APPC print sessions, change "PRINTSESSION3270" to "PRINTSESSIONAPPC" in each command.
The following sample SNACFG command enables the "Use fixed font size" option for an existing 3270 print session that is named PRINT1:
Note You must specify a specific font and a specific font size together with the /FONT parameter and the /FONTSIZE parameter to enable the "Use fixed font size" option.
If you specify the /OVERRIDEFONTSIZE:Yes parameter for a print session that is not configured to use a specific font and a specific font size, the SNACFG utility returns the following error message:
Undefined parameter FONT Undefined parameter FONTSIZE Required parameter missing or parameter value invalid Command failed
You can use the following SNACFG command to enable the "Use fixed font size" option when the specified 3270 print session has been previously configured to use a specific font and a specific font size:
Similarly, you can use the following SNACFG command to disable the "Use fixed font size" option when the specified 3270 print session has been previously configured to use a specific font and a specific font size:
