|Ha! I love both the creepy printer and the ending using the image of the newspaper headline... well done! The monster in the shadows is more terrifying than the one in the light. As a writer, losing a 98-page story might be more horrifying still! :)
Here are a couple of things that I think might help make this nicely twisted little tale even better!
1. Joe starts off tired, but he just achieved something great! Maybe tweaking the start to something more dynamic to SHOW a little more and tell a little less. It might also make him more likeable/relatable to the reader. This is what I'm thinking:
"Joe was tired. Very tired. His hands ached from all the keyboarding he had done beginning early in the morning."
...becomes something a little more dynamic/descriptive along the lines of...
"Joe's chin hit the keyboard, shocking him back into consciousness. Even now, however, his eyes drooped and his hands ached from twelve straight hours of keyboarding."
2. Involving more senses makes the writing more dynamic and memorable as well. For example:
"Just as he was about to pour two fingers into a shot glass, he heard a sudden sound. Joe spun around looking for the source of the sound. The bottom of the bourbon bottle knocked the glass onto the floor."
...becomes something more like...
"Just as he was about to pour two fingers, a massive crash rattled the glass on the bar, causing it to clang against the bottle of bourbon. Joe spun, eyes seeking the source of the sound. His elbow caught the bottle, sending the glass rocketing to the ground, shards of glass exploding over the floor like crystalline fireworks.
Anyway, I hope that helps. In extremely short fiction like this, you have only a thousand words to make a real impression on the reader, so you want to make it as dramatic as possible.
Your story itself is great, I love it! If you involve a few more senses and images, I think it will be something really special. I hope this is helpful. I can't wait to read more from you...
