How can I load PCL font using command line?

Question

We have a software that requires a signature font to be uploaded to the printer beforehand.  if the printer power cycles, the font is lost and paper is wasted.  This usually happens when a brown out occurs overnight.
Our font vendor has a command line windows software that can upload the font to the printer.  It costs 100.00. 
I'd really love to find a way to upload this file using linux.  The page is generated on linux so i could incorporate the command into that process.
Anyone know of free software to do this on linux or windows?  or maybe programming documentation?

i think i found the answer on another site

Configuration 2: Network Printer Server
When the printer is connected to a TCP/IP network directly, the best method is to send commands through lpr command. A TCP/IP device may be identified with a full qualified DNS name, or an IP address. In our test lab, we assigned our network printer a fixed IP address 192.168.1.22, and we use this address in the examples below. Inlpr manual page, it is also referred as Printer Name.
Another name you will need is Queue Name. The queue names are names assigned to the “processors” in the print server. Many print servers and network printers hardcode their queue names. Some allow you to define your own queue. On HP JetDirect printer servers, the raw PCL queues are named as raw, raw1, raw2 and raw3. In this article we use rawas the queue name.
Note thatlpr command only accepts 1 file at a time. However, the step1 and step2 commands must be sent in one stream, otherwise the printer discards them altogether. As a result, you will need to merge those three files into one first. On Windows, you can use copy command:
copy /b C80D.txt +mrvcode39_4pitch.sfp +c5F.txt total.bin
On Linux/Unix platforms, use cat command:
cat c80D.txt mrvcode39_4pitch.sfp c5F.txt > total.bin
Now we can send these files (Windows):
lpr -S 192.168.1.22 -P raw -ol total.bin lpr -S 192.168.1.22 -P raw -ol data.txt
You need to replace the IP address, the queue name and the file name with the appropriate ones in your environment.
On Linux/UNIX platforms, things are more complicated. The configuration varies from platform to platform. Generally you need to set up the printer first. On RedHat Linux, this can be done using printtool. You assign a printer name (queue name) in the configuration, and you use this name in lpr command. Assume that the name is HPPrinter, the lpr command on RH Linux becomes:
lpr -P HPPrinter -o raw total.bin lpr -P HPPrinter -o raw data.txt
