I'd sway to the yes side.
I agree with user568458's comment that questions on related to commercial printing or silkscreening could be beneficial.
However, I'd also say that Photographers, designers,and artists often print to their own high-end printers to create prints for sale. Stock used in this workflow would equally be on topic to me.
In addition, there are many small shops running equipment like oversized printers or Fiery Rips and that would also make the questions on topic to me.
But.... "what paper she we use in the office printer" would be off-topic.
