Supressing new-lines in awk output

[Larry Dighera]

Is there a way to supress the newline at the end of awk's print output?

Given:

	awk '{print $1}' filename

Where filename contains:

	field1.1 field1.2
	field2.1 field2.2
	field3.1 field3.2

awk will print the first field of each record on a seperate line:

	field1.1
	field2.1
	field3.1

Is there a way to cause each "$1" to be printed with a space delimiter instead,
such that the output would look like:

	field1.1 field2.1 field3.1
