Question: What is the dimensions of the printer shelf?
Document: At the back I have placed a small white board. The printer sits comfortably on the shelf designed for it. This desk turns a small corner into a comprehensive work station - almost a compete office in itself.
As it turned out, there is ample space on the desk top because the printer shelf is set back about 10" from the front. Great design. In reality, the desk top has a lot of space.2. The second issue was a bit of a surprise, because I didn't expect it.
My mom needed a computer desk that would fit in her bedroom in her new apartment. I researched alot of them and finally decided on this one after looking all over in stores and on the internet. This desk is relatively easy to assemble, looks great and is very sturdy/well made. She has a mac so she doesn't need the lower shelf for a cpu. We put computer books on the lower shelf and it works great for that. The printer fits very well on the printer shelf.
I like this solution because it includes a printer shelf, scanner tray. and a drawer to put stuff in. Plus it looks nice. The lamination might be a bit bubbly along the edges but it doesn't bother me much. Seems to be a solid-enough unit.Assembly-wise I have never seen a do-it-yourself kit with parts labeled so completely; even the drawer slides were labeled RIGHT and LEFT (for those who wouldn't know otherwise?). It even came with extra screws!
The drawer I use just for printer paper. The tower shelf I use for a small cabinet which comprises, a small drawer for various spares (such as printer cartridges and spare USB cables), three file storage slots which will also accommodate thin books or boxes (of envelopes for example) and an open half height slot for bulkier items (box of business cards). This is a simple self assembly cabinet from one of many retailers such as (Hobby Lobby, Walmart, Target, Office Depot etc).
I will be checking out other Knock-down furniture this company makes, I am also looking for a book shelf/case.
I like the drawer for my stuff.Use the CD/DVD storage to organize my DVD's.Use the pull out shelf for my inbox mail.I recommend this desk.
As mentioned above, the shelf is set back about 10" from the front edge of the desk which frees up a significant amount of space on the desk top itself. I have two printers that fit without a problem - the larger measures 15-1/4" wide by 13-1/4".
For such a platform, the added 2-1/2" projection of the keyboard tray from the front end of the slide allows the platform to be attached to the side end of the tray rather than to just the front end. It can also be easily swiveled out of the way for sliding open the drawer or top shelf of the desk when either are needed.
But from the center-front of the keyboard, the reach distance to the shelf which holds the mouse turned out to be continually uncomfortable for me - even before I readjusted the keyboard. So I purchased a clamp-on mouse platform that attaches to the  keyboard tray and is easy to reach. It also can be swiveled under the keyboard tray. Some people like these mouse platforms as I do ... some do not.
