SNA Server Print Service Doesn't Support Print Position > 132

This article was previously published under Q172468


Print Server inserts a new line (NL) character after print position 132, even if the default page width is set to a value greater than 132.


Microsoft has confirmed this to be a problem in SNA Server version 3.0 Service Pack 1 (SP1). This problem was corrected in the latest SNA Server version 3.0 U.S. Service Pack. For information on obtaining this Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):



Previously, LU3 printing had a maximum line length of 132 characters. With the fix applied, you can specify the line width, using the SNA Server Manager.

NOTE: The maximum print position (MPP) supported in the code is 255 characters, but you can specify any value in the SNA Server Manager. This change also includes code to set the MPP to 255 if you specify a value greater than this.

The IBM 3270 Datastream Programmers Reference, page 2-22, says:

The NL order is executed only when encountered during an unformatted printout; this is, a printout that does not have a line-length format specified. When an NL order is encountered in the buffer, the priner performs an NL function. If no NL order is encountered before the printer reaches the end of a line (as determined by the maximum print position), the printer automatically performs an NL function and continues printing.

If an NL order is encountered at one character position past the maximum print position, the 3230,3268,3284,3286,3287 and 3288 printer will perform two NL functions; the 3262 and 3289 printers will perform one NL function.
