Chapter 15 Complete Command List set prn flush Flush the data in the parallel port input and output buffers. set prn unlock Release the access lock on the parallel port. set prn timeout minutes |none example: set prn timeout none Terminate the print job sent to the parallel port if it is not printed after the timeout period in minutes expires. The minutes value ranges from 0 though 255, with 0 indicating no timing out to take place. This is the default setting and should be fine for most print setups. set prn [-]opost example: set prn -opost Allow or disallow output processing on the parallel port such as carriage return insertion (e.g., onlcr). set prn [-]onlcr example: set prn -onlcr Enable or disable carriage return insertion on the parallel port. This may be needed for Unix text jobs coming through with solitary linefeeds. This feature is almost always set at the model level rather than the I/O port level. set prn xtab tablength |none example: set prn xtab none Set the tabstop width as indicated by tablength. The range is 1 through 16 spaces. set prn from default Set all parallel port settings back to factory defaults. set prn from stored Set all current parallel port settings to the values stored in flash memory. 272
