If you have GNU sort you could try the stable sort option (-s):
That would keep the relative order of the 4th column for records with the same first three columns unchanged like you asked.
But your output sample seems to only group the same records without changing the order in which the records appear for the first time. Is that what you are after?

I know that to create a pdf file I can use the txt2pdf command.

join
JOIN(1) User Commands JOIN(1)NAME
join - join lines of two files on a common field
SYNOPSIS
join [OPTION]... FILE1 FILE2
DESCRIPTION
For each pair of input lines with identical join fields, write a line to standard output. The default join field is the first, delimited
by whitespace. When FILE1 or FILE2 (not both) is -, read standard input.
-a FILENUM
print unpairable lines coming from file FILENUM, where FILENUM is 1 or 2, corresponding to FILE1 or FILE2
-e EMPTY
replace missing input fields with EMPTY
-i, --ignore-case
ignore differences in case when comparing fields
-j FIELD
equivalent to `-1 FIELD -2 FIELD'
-o FORMAT
obey FORMAT while constructing output line
-t CHAR
use CHAR as input and output field separator
-v FILENUM
like -a FILENUM, but suppress joined output lines
-1 FIELD
join on this FIELD of file 1
-2 FIELD
join on this FIELD of file 2
--check-order
check that the input is correctly sorted, even if all input lines are pairable
--nocheck-order
do not check that the input is correctly sorted
--help display this help and exit
--version
output version information and exit
Unless -t CHAR is given, leading blanks separate fields and are ignored, else fields are separated by CHAR. Any FIELD is a field number
counted from 1. FORMAT is one or more comma or blank separated specifications, each being `FILENUM.FIELD' or `0'. Default FORMAT outputs
the join field, the remaining fields from FILE1, the remaining fields from FILE2, all separated by CHAR.
Important: FILE1 and FILE2 must be sorted on the join fields. E.g., use `sort -k 1b,1' if `join' has no options. If the input is not
sorted and some lines cannot be joined, a warning message will be given.
