Troubleshooting

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.
