Your problem is most likely the printer not sending XOFF.  I see no
problem with your printcap entry.  I'm not sure if it will help, but I've
included the printcap entry we use on our HP pen plotter which needs
XON/XOFF to run at 9600 bps.

Note that the HP 7750A can be programmed to use XON/XOFF by sending the
sequence "\033.P1:" or by front panel selections.
