Troubleshooting
B - 7
B.6.1 Bitmap Graphics
If Þles that contain embedded bitmap graphics print incorrectly, it is because the bitmaps
are being sent as actual binary data and binary data cannot be printed via serial or
parallel interfaces.
Most major application packages have provisions to print using either Òbinary
postscriptÓ (for printers connected to the network via LocalTalk) or Òhex postscriptÓ (for
printers connected to the network via a serial port or parallel port). If your application
does not have this provision, ask the application vendor for an upgrade version or
ÒpatchÓ that will add the Òhex postscriptÓ function.
Port Counters If PostScript jobs appear to print but nothing comes out of the
printer, verify the amount of data sent from the host. Issue the
appropriate print command from the host system. After the job
has completed, use the Show Port 1 Counters command.
The bytes output value should be approximately 171 bytes
greater than the size of the Þle on the host system. These
numbers are only approximate, but will show that data is
ßowing to the printer.
