HP 3000s generate Printer Command Language, the format syntax HP created for its line of laser printers. The 3000s were glad to get PCL abilities in their applications and utilities, but PCL is not for everybody. Multifunction devices not schooled in HP technology, such as those from Xerox, need a go-between to extend the 3000's printing.
The easiest and most complete solution to this challenge, one recently posted on the 3000 newsgroup, is Minisoft's NetPrint, written by 3000 output device guru Richard Corn. When we last reported on Corn's creation it was helping the Victor S. Barnes Company pass 3000 output to Ricoh multifunction printers.
But for the company that can't find about $995 in a budget for that 3000-ready product, there's a commercial Windows alternative of about $300 less you might try to integrate into your system designs. Charles Finley of Transformix explains that the path to print outside of PCL is two-fold.
Finley says of the fundamentals:
1. You need to get the print output from the HP 3000 to some device that is external to the HP 3000
2. You may need to intercept the PCL generated on the HP 3000 and format it for the intended device.
On the one hand, you can license the product of either Richard Corn or Minisoft to manage all this -- or if you want to use what MPE provides, you need to intercept the stream by using something that pretends to be an HP LaserJet.
In the second scenario, assuming you can connect the printers to Windows computers, you can use LPD and an interceptor of some kind. A commercial product we have used is RPM from Brooks Internet Software to accomplish the communication part of the process, plus some other PCL translator product to convert the PCL to whatever you need on the printer.
We had two projects in which, instead of the RPM product, we provided our own little interceptor (described at www.xformix.com/xprint) that does the same kind of thing as RPM. We have the Windows machine pretend that it is an HP PCL printer and configure the HP 3000 to print to it. We used other commercial software (two different products) to intercept the output intended for what it thinks is a LaserJet and format the print output so that it prints correctly.
I believe in each case the customers wanted to translate the PCL to PDF and do other stuff with it on the Windows computer before actually printing it. In one case, they wanted to store the PDF on the Windows computer and store reference data in a SQL Server database so that customers could selectively view and print the file at will.
