If you can start going through a office supplies blog, you will see exactly how to go about printing a higher volume of documents in the office as opposed to going to an outside source for these types of needs. Ultimately, this is going to save you tons of money, and you might be even more satisfied with the level of quality you are able to produce as opposed to someone else. The quality of your prints is directly related to your printing supplies, however, so you should keep this in mind as you do your shopping.
However, if volume of printing is your main consideration, you could also check out an office supplies blog that deals with getting the fastest prints possible. There are some simple tricks of the trade that will make it easy for you to achieve this goal. For instance, you could change some of the color settings on your printer to black and white in an effort to improve overall speed.
Or, you could switch the quality setting to standard rather than highest quality if you know something is going to be used solely within the confines of your office. The highest quality setting also tends to use more ink, so you will want to be sure that you are not unnecessarily wasting this precious commodity on a document no one is going to see.
Finally, you will want to print a high volume at the lowest price possible, especially if you know that your office is on a rather tight budget these days. You will want to do some price comparison, and make sure to include online stores in your overall assessment of what you need. The online stores quite often have prices that you would simply not see anywhere else.
