Dear Rick,

The specification for the parallel ports on PC printers is known as IEEE 1284. 
The original specification was approved in the 1994 timeframe. Since that time, 
some IEEE committees have been working on enhancements to the original 
specification. The enhancements are known as "dot" specifications because the 
terminology adopted by IEEE for the enhancements in production is IEEE 1284.n 
where n can be a number greater than or equal to 1. It happens that printers 
with parallel ports that conform to the IEEE 1284.1 enhancement specification 
can confuse the parallel output port on a 3487 terminal so that it does not 
properly understand the condition of the printer causing the result that you 
have observed. We have seen the same phenomenon with the Praim logic units we 
support (5488 Plus) and have had to open a service request with Praim 
engineering to enhance the operation of the product to be compatible with these 
newer printers. The suggestion for you would be to contact IBM support to see 
whether any 3487 microcode updates are planned to address this hardware 
compatibility issue.

Subject:        HP 1100 Printer - IBM 3487

I connected a HP 1100 laser printer to an IBM 3487 terminal which is attached 
to an IBM 5394 controller.  I can configure the printer, start the writer, and 
send print files to it.  The AS/400 says it printed okay.  However, the printer 
never prints.  Any suggestions?
