MPS/LPS User Guide B: Troubleshooting
B-6
Area to Check Explanation
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 file on the host system.
These numbers are only approximate, but will
show that data is flowing to the printer.
Bitmap Graphics
If files that contain embedded bitmap graphics do not print
correctly, it is probably 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 binary postscript (for printers connected to the network via
LocalTalk) or hex postscript (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
“patch” that will add the hex postscript function.
