A computer or laptop per se is a hardware and need a special software to do the task expected from it. A parallel analogy is that of a car (a real hardware) that will need a driver to move around. The driver in the analogy is the operating system (OS) uploaded into the computer that makes doing tasks possible. The OS is a software that controls and tell the computer how to operate: controls the hardware, executes programs, manages resources, assign tasks, and gives the user an interface through the computer to monitor the work at hand.
A computer will need several software to do multi-tasking feats, like a software each for printing, documents storage, mail sorting, photo printing and several others. In printing alone, software is numerous because there are a lot of printing requirement. From business cards’, to flyers, to restaurant menus, to outdoor advertising, to label printing and much more.
It would come out expensive if each task is provided with a computer and a printer. All the different software is bundled into the computer and the user will simply need to access the application to do a task. And due to the existence of the Internet, a series of computers can now be banked together to be served by only one printer.
The HP LaserJet Pro 400 m401dn is one printer that is designed to handle all tasks thrown at it. Considering that it serves series of computers it can ably meet printing from different software programs. The process is possible because the printer operates with a firmware that allow document queueing. All documents are lined up and printed one at a time.
Printing from different software program though complex as it sounds is a simple matter even for banked computers. A computer must simply need the necessary drivers uploaded to deal with any printing requirement. Photo print job for example can be done with a compatible driver, and once the print job is complete the user can proceed with other print task using another appropriate software.
Treat printing from multiple software program the same way a single printing job is accomplished. Printing irregularities even on an HP LaserJet Pro 400 m401dn can happen only, if the system does not run on effective drivers. Updating an HP driver to a new version is the only solution to resolve the issues. And these updates are available free online as a direct response from manufacturers and software designers.
How the HP LaserJet Pro 400 m401dn printer prints from different software programs was never an issue, drivers were developed precisely for this.
