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 approx-

 

 

imate, but will show that data is flowing to the printer.

 

 

 

I.6.1 Bitmap Graphics

If files 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 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.
