Ok, I don't get out much, so this capability might already exist.

When I want to print, on my Brother printer, a file at 12 CPI instead of 
the default 10 CPI, I edit the file and place a sequence of characters 
at the front to cause the printer to switch to 12 CPI, for that job.

Sure would be nice to:

$ PRINT /QUEUE=LASER /CPI=12
