Printing from M/F COBOL

Hi Chaps

An avid reader of this forum for years. Very interesting at times.

I have a question I am sure somebody can help me with.

I currently look after a customer who use all HP laser printers. 20
years ago we embedded PCL code to control these printers. Setting
landscape/portrait, duplex pages, the odd underline and bold bits.
When we moved to M/F Netexpress 3.1 we adopted the PC_PRINTER routines
and send a 'raw' file to the printer. I now have a new 'customer'
asking for some system and I am going to need to print for them. I
can't expect them to use HP printers here so what are my options. I
assume the PCL language is a HP thing and other printers won't
understand it.

Any ideas?

Thanks

Rud
