Printing a job
PrintOpen must be the first function call
in every print job. The PrintOpen function defines
a new blank page in memory, specifies that all printing be done
in the printer’s default font, and returns an integer.
The integer is the print job number that is used to identify the
job in all other function calls.
PrintOpen is followed by calls to one or
more other printing functions, and then the job is ended with a PrintClose (or PrintCancel)
call. The functions you call between the PrintOpen call
and the PrintClose call can be simple print functions that
print a string with or without tabs, or more complex functions that
add lines and objects to the report or even include a picture in
the report.
Printing titles To print a title at the top of each page, keep count of the
number of lines printed, and when the count reaches a certain number
(such as 50), call the PrintPage function, reset
the counter, and print the title.
Here is a simple print request:
|
1 |
Int PrintJobNumber |
|
1 |
// Start the print job and set PrintJobNumber to |
|
1 |
// the integer returned by PrintOpen. |
|
1 |
PrintJobNumber = PrintOpen() |
|
1 |
// Print the string Atlanta. |
|
1 |
Print(PrintJobNumber,"Atlanta") |
|
1 |
// Close the job. |
|
1 |
PrintClose(PrintJobNumber) |
