The printing problems are indeed probably related to the printer driver.
In addition to running output through the various printer drivers
(Imagewriter, Laserwriter, whatever 3rd party driver you've selected in
the Chooser), both 4D 1.x and 2.x (the current shipping version is 2.08)
allow a direct data feed through the serial port of your choice.  In 
general, this is MUCH faster than operating through a print driver,
and 4D 2.x does this much more elegantly than 1.x did.

Unfortunately I don't have my 2.0 docs handy just now, or I could refer
you to the chapter and verse where this is covered.  In my experience,
though, a direct serial feed often eliminates some of the problems
associated with printing to dot-matrix machines.  You do lose the
ability to have fancy fonts and such, I should add.
