HP Printer Command Language 4.5(PCL 4.5)

By mln ·
We are using an emulation package that allows our users to view the database in a Windows environment. Some of our programs contain the HP PCL commands, which are being used to print certain 132 character reports in compressed mode to the local PC printer (LPT1). We are using NEC Superscript 870 as local printers on the majority of our PCs. It seems that every so often the printer needs to be power-cycled before it will recognize the PCL commands. I have (2) HP LaserJets and (1) Samsung ML-1250 that don't need power-cycled. The only difference between the printers is that the NEC printers are compatible with version 4.5 and the others are compatible with 6.0. Does anyone have any explanation as to why this is happening? And a solution?

Thanks.

It would depend on where the data is coming from. Is it coming from an AS400 or IBM Unix? How is it routed through the users LPT port? if it is a dos job going through the lpt port, there probably isn't a whole lot you can do. If the data is coming from a mainframe or unix server and is being routed through the local pc's then it is using the windows print driver(usually for the default printer). In that case you can try loading a generic hp 4 driver. It could be that some of the HP PCL commands are conflicting with commands from the local print driver. hope this helps.
