My nerd side objected to the artistic license there. The computer programmer character should know it's instructions to the user (necessarily terse on a very small character display), to load more blank US Letter size paper into the Paper Cartridge.
What a programmer would more likely be complaining about with a corporate workgroup page printer is someone spooling a huge job that DoSes it, piles of other people's printouts that they never picked up, toner out (and it's not in a sealed cartridge, so you're risking staining your clothes and hands as well as the carpet), paper jams (including paper that must be ripped out, and job reconstructed, after backlog of others' jobs), failing pickup rollers, some software they have to use that sometimes overloads the renderer RAM, the smell of ozone from heavy printing with no openable windows, etc.
