I am using this printer and this computer several years ago.

This defect appeared only after a recent upgrade of Linux.

Before the upgrade, the printer worked well and the programs that generate text files are the same.

For this reason, I do not think the problem is in printer

I try to print simple text files, and they are generated within dosemu.
