I'm going to go with the earlier contributors to this thread and suggest that paste is your best option at the moment.

You don't say anything about the system, not too mention the printer. A 4Gb file given your example of 6 chars per line would run to roughly 8 Million pages, this is going to take some time to print. So repositioning all the pages in the right order and running through the printer would be quite a task not to mention somewhat time consuming.

It starts to get really complex if you want to print a file and then run the same paper through the printer a second time printing at potentially a different start position for each line.

Twelve Characters per line and Sixty Six lines per page, assuming printing on A4 paper using standard spacing would give the following ;

Pages in the file = (1024x1024x1024x8)/(66*12) = 10,845,000 Pages.

If you have a printer capable of 20 Pages Per Minute then 540,000 Minutes or 9,000 hours or 376 Days.

Post the output from below and we can take it from there.

Code:

#> LINES=`wc -l ${filename} | awk '{ print $1 }'`
#>echo ${LINES} / 66 | bc

As to the how to do it, well.

Code:

[root@fbakirpomd4 ~]# cat test_01.txt
abc
def
ghi
[root@fbakirpomd4 ~]# cat test_02.txt
123
456
789
[root@fbakirpomd4 ~]#
[root@fbakirpomd4 ~]# paste test_01.txt test_02.txt > test_03.txt
[root@fbakirpomd4 ~]# cat test_03.txt
abc     123
def     456
ghi     789
[root@fbakirpomd4 ~]# paste -d "" test_01.txt test_02.txt > test_04.txt
[root@fbakirpomd4 ~]# cat test_04.txt
abc123
def456
ghi789
[root@fbakirpomd4 ~]#

You originally wanted to print two files with the contents side by side, now you want to print the first file in it's entireity with the first line of the second file appended to the end of each line - is this correct?
