El excel no reconoce las impresoras conectadas

Pascual5 

First try to print another document with another program.

This will help you determine if the problem is with the printer or with Excel itself.

Before taking any further steps, restart the computer.

The problem may resolve itself.

Make sure you have selected the connected printer.

Print jobs can inadvertently arrive at printers that are offline.

Some printers cannot process unusual characters or fonts.

If you use them, change them if necessary.

If you have created a very large table, try splitting it into two files as a test.

Additionally you could:
perform Office update,
perform office repair,
Disable add-ins.

Hope I could help you with these information / links.
