Printer driver Error handling
Log file
Print file
The log file contains all driver settings. The most important section is
at the end of the file.
The clear text indicates the text which is to be printed.
Example: 'Ein Text in Swis721' and 'Ein anderer Text in Arial'.
Moreover the paper form is indicated.
Example: 100 x 30 mm.
The following extract shows the appropriate prn file. The label format
100 x 30 mm is also recognisable. In addition it is obvious that from
the text formatted in printer font Swis721 a mask set was created.
The apparently unsystematic character sequence SOH NUL ETB ESC
B NUL etc. belongs to the bitmap graphic that was created from the
'Arial' text.
The prn file shows the data stream which the driver sends to the
spooler and/or to the printer. It is composed of parameter sets (printer
and document settings), graphic data, mask sets (print objects) and
the actual print start.
