Selecting certain paper types or printing in higher quality can slow print speeds. Print with plain paper in reduced quality for faster print speeds. Search Windows for printers , and then click Printers & Scanners in the list of results. Click your printer, and then click Manage > Printing preferences.
Check Ink or Toner Cartridges & Paper Tray

Issues in your printer`s ink or toner cartridges as well as an empty paper tray can cause your printer to delay your prints. Make sure that your cartridges are not running out of ink and the paper tray is not empty.

Risks of printing too slow

In general, a slower 3D printer print speed results in higher quality. Nonetheless, printing too slowly can cause issues of its own. These issues generally relate to overheating: if the filament stays in the nozzle chamber too long, it can get too hot and cause deformations on the part.

If you feel that the ink cartridges run out very quickly every time you replace the ink, it`s possible you are printing high density documents frequently. The ink consumption varies very much on print density.
Current inkjet printers does use a “spray-gun” type of ink transfer, which means the spray-gun (nozzles) has to move over the paper in a similar fashion to when you use a spray-gun. Unless the printer has a `spray gun` large enough for (covering) the width of a page, or an entire page, the speed will always be slower.
The Print Spooler is software built into the Windows operating system that temporarily stores print jobs in the computer`s memory until the printer is ready to print them. In some circumstances you may need to stop and/or restart the service.
Slow prints are usually caused by sluggish or out of date software or a spotty wireless connection. For a quick fix, make sure that all of your printer drivers and printer software is up to date.
Write down the two times from the stopwatch. The first time tells you how long a one-page document takes to print. If the second time is greater than one minute, convert the time to seconds and divide seconds by four. The result is the average time, per page, for a long print job.
A printer`s printing speed is simple: it`s how quickly it can produce properly printed pages, whether they`re black-only documents, color documents, or photos.
Check Your Print Settings

Many printers have options for printing at different speeds—for example, you may be able to choose between “normal” and “draft” mode. Draft mode will usually print documents faster than normal mode, but the tradeoff is that the quality of your prints may suffer somewhat.

There are several factors which limit 3D printing speed such as firmware settings, frame stability, flow rate of material, what material you are using the type of printing and much more.
