Character Group - Star Micronics 4111 Applications Manual

If your Star LaserPrinter 4111 doesn't print what's on the computer screen,
recheck your connections and interface settings. With an applications
program like Lotus 1-2-3 or Microsoft Word, you use a printer setup routine
to match your computer with your printer's operating characteristics. So
double-check your software settings; your computer's output, for example,
might not be going to the proper port.
2.2.3 Hints: The hex dump
To make your Star LaserPrinter 4111print in hexadecimal rather than the
usual ASCII symbols, press the control panel buttons that put the printer
offline and in PROGRAM mode. Move to the EMULATION parameter's
HEX DUMP setting and select it.
Some control or Escape codes can be problems on a few computers; those
computers change certain codes when sending them to the printer. If you
think you have this problem you need to see exactly what your printer is
receiving. We recommend you run a short program that loops through and
prints the ASCII table. Print in hexadecimal rather than the usual ASCII
symbols.
If you spot a problem code you can try to bypass the problem, either by
sending each code directly to the printer, or by changing your system's
printer driver. Such computer-specific solutions, though, are beyond the
scope of this manual. We suggest that if necessary you consult another
programmer more familiar with your computer.
Actually, if you are debugging any program you may find this hex-dump
mode helpful. It can be a great trouble-shooter.
