JetDirect is based on HP's MIO (Modular Input/Output) interface, which was designed from the ground up with the IIIsi to create a mainstream full function high performance networked printer. The initial MIO interface card had Ethernet and Token Ring physical layer variants and used various networking protocols over an AUI / BNC connection.
The New York Times quoted a technology analyst's view of the 5520 as "a competitive product in(to) a rapidly growing field." [1]While the Office System/6 introduced two years earlier by IBM Office Products Division (OPD) was focused on word processing, the new 5520 intended to complement existing products lines with text editing and data processing power.

HP Roman-8 is an 8-bit single byte character encoding that is mainly used on HP-UX [2] and many Hewlett-Packard [7] and PCL compatible printers. The name Roman-8 appeared in 1983, [ 1 ] but a precursor of the character set was already used by the HP 250 and HP 300 workstations since 1978/1979 as 8-bit Roman Extension .
A printing protocol is a protocol for communication between client devices (computers, mobile phones, tablets, etc.) and printers (or print servers).It allows clients to submit one or more print jobs to the printer or print server, and perform tasks such as querying the status of a printer, obtaining the status of print jobs, or cancelling individual print jobs.
As its name implies, an HP-IL network formed a loop (i.e. it was a Ring network): each device in the loop had a pair of two-wire connections, one designated in, which received messages from the previous device in the loop; and one designated out, which delivered messages to the next device in the loop.
After the release of the initial models in 1993, new models started to become available as the Presario brand grew over time. The 500, 700, and 900 series (including the 5500, 7100, 7200, 9200, 9500, and 9600 series) were introduced to compliment and succeed the original lineup, making up the first generation of Presario computers produced from 1993 to 1996, also known as "Series 1".
Some modern xenon flash units have the ability to produce a longer-duration flash to permit flash synchronization at shorter shutter speeds, therefore called high-speed sync (HSS). Instead of delivering one burst of light, the units deliver several smaller bursts over a time interval as short as 1/125 of a second.
