Printing PCL Files from OpenVMS
Barcode Basics >
Notes > AppNote033
Printing files that are encoded in PCL ("Printer Command
Language", supported by virtually every laser printer
manufactured) often requires special handling. PCL files
contain control codes that are part of the commands that tell
the printer what to do; the operating system's print drivers
often want to strip out the control codes and do it "better".
The result can be that printed documents do not appear as was
The solution is to include a command-line parameter that
tells the print driver to stop being so helpful and just pass
the contents of the file (control codes and all) to the printer.
On the OpenVMS operating system the magic parameter is /PASSALL:
PRINT /PASSALL myfile.pcl
