How can I install printer drivers without having a printer?

Congratulations on the purchase of your new laptop. Apparently, from your question, it looks like that you want to install drivers for printers prior to actually buying a printer and connect to your computer. Just so you know, this idea can go really wrong and later your new printer may not work at first. You need to understand the fact that a certain printer from a specific brand has a certain driver and not a generic one that can be used for any printers available in the world. Different printer makers have numerous different features available on their printers which can not be matched by a single set of generic drivers. Consequently, any printer of any make can't work with a single driver. I would like to advice you that you should first buy your new printer based on your requirement and install the accompanying driver on your computer. If you want to stay updated (that's also recommended). Please download the required drivers from your printer manufacturer's website and install them to achieve full stability and functionality on your printing device. Installing generic, old and outdated drivers are not at all recommended and though at times they offer some functionality, there are little chances that you will achieve the true potential of your new printer.
