I echo some of Eric's suggestions, but I'd also add these comments:
Your ASM program source says this is distributed under the GNU GPL:
;The following code is based on the IEEE-1284 probe code from Linux, which was
;written by Phil Blundell, Carsten Gross and Jose Renau and on Turbo pascal
;translation by unknown author.
;Implementation in assembler (TASM 4.1) is written by Laaca
;I am not sure about timing of signals because original source claims that it is
;important but it was difficult to rewrite in assembler preciously.
;This program can be spread under conditions of GNU/GPL licence.
You need to also include a copy of the GNU GPL with a copy of your
program. To do so, put the following notice at the start of each
source file; each file should have at least the "copyright" line and a
pointer to where the full notice is found. I'm using the GNU GPL v2
here, since the Linux code you reference (derived from) is still
covered ONLY BY GNU GPL v2.(**) Therefore, it would be inappropriate
to automatically promote this derivation to GNU GPL v3.

Since your program displays to the screen, it should output a short
notice like this, usually in a "Help" screen:

(**) Just for reference, I grabbed the latest Linux kernel source, and
found this note in COPYING:

And the two kernel source files that do 1284 don't mention a different
GNU GPL version (it mentions code snippets may be used in
documentation under the GFDL 1.1 or later, but that is not a source
code license.)
