Bokeh's Python API function export_png can grab an entire document in one PNG, including grid plots. Otherwise I think you would have to look at coordinating Selenium and a headless browser to capture an image (which is all export_png does under the covers, anyway).
I can't think of any current way to be able to do this from within the browser, i.e. with a plot tool.

The following code works just fine using the export_png() method:
import numpy as np
from bokeh.layouts import gridplot
from bokeh.plotting import figure, show
from bokeh.io import export_png
plots = [figure(plot_height = 200, tools = ‘save’) for i in range(15)]
[plot.line(np.arange(10), np.random.random(10)) for plot in plots]
all = gridplot(plots, merge_tools = True, ncols = 3, sizing_mode = ‘scale_width’, toolbar_options = dict(logo = None))
export_png(all, filename = “gridplot_new.png”)
show(all)
