Postscript printing enables one to either print the data currently on the screen or use slave printing to print to a Postscript printer.
Postscript printing is enabled by setting Slave Printer Data Conversion option to Graphics. This is done in the Terminal -> Setup menu -> Printing tab. If this is the case then slave printing to a postscript printer will work whether Print Device is set to File, Device, or Print Manager. However, if the Slave Printer Data Conversion option is set to none and Print Device is set to File, slave printing will fail and PowerTerm will appear to be hung. Screen printing to a Postscript printer will be successful if Print Screen Data Conversion is set to Graphics in the Terminal -> Setup menu -> Printer tab.
