Pulsar was created out of frustration in switching between the PostScript & PCL modes on our Company HP LaserJet printers under the Windows environment. Our printers here are equipped with the PacificPage postscript cartridge and normally would require a command string be sent via DOS and then running Window's Control Panel to get Windows in sync with our mode intentions. We spent many-a-time and lost many-a-page sending printouts to the 'wrong' printer thinking it was being sent to the PostScript when it was actually being sent to the PCL and vice versa, so we wrote Pulsar to simplify the matter.
