Mavriky Nikolaevitch wants to go out and forbid him to do it.

As I have looked upon you as a colleague," she turned to Shatov, "and as you live there, I wanted to question you so as to judge what more is to be expected of him." "He's a drunkard and a worthless fellow," Shatov muttered with apparent reluctance.
"Is he always so stupid ?" "No, he's not stupid at all when he's not drunk." "I used to know a general who wrote verses exactly like that," I observed, laughing.
"One can see from the letter that he is clever enough for his own purposes," Mavriky Nikolaevitch, who had till then been silent, put in unexpectedly.
"He lives with some sister ?" Liza queried.
"Yes, with his sister." "They say he tyrannises over her, is that true ?" Shatov looked at Liza again, scowled, and muttering, "What business is it of mine ?" moved towards the door.
"Ah, stay!" cried Liza, in a flutter.

"Where are you going?
We have so much still to talk over...." "What is there to talk over?
I'll let you know to-morrow." "Why, the most important thing of all--the printing-press! Do believe me that I am not in jest, that I really want to work in good earnest!" Liza assured him in growing agitation.

"If we decide to publish it, where is it to be printed?
You know it's a most important question, for we shan't go to Moscow for it, and the printing-press here is out of the question for such a publication.

I made up my mind long ago to set up a printing-press of my own, in your name perhaps--and I know maman will allow it so long as it is in your name...." "How do you know that I could be a printer ?" Shatov asked sullenly.
"Why, Pyotr Stepanovitch told me of you in Switzerland, and referred me to you as one who knows the business and able to set up a printing-press.
