Talk:Standards

Is this a discussion page for possible standards for this printer, or a list of those which will be implimented?

As for the connector, this is a decision which will hinge upon the choice of hardware used to run the printer. USB, for example, has the advantage that it is extremely common and flexible, but has the disadvantage of having a relatively complex protocol. Parallel and serial, on the other hand, use a simple protocol, but are very rarely available in modern computers. As such, USB is suited to higher-level hardware/software implementations, while parallel and serial are very well suited to platforms such as microcontrollers

USB Parallel
Parallel (or seriell) is 100% OK and sufficient, but there shold be a (certified) "USB->Parallel LPT Cabele Adapter - Centronics" (or USB2Seriell).

Maybe the system could be build with a recycled PC-x86-Motherboard. (-Lot of bang for the bug, with Wake-on-LAN also energy efficient)

To keep it simple - A, LPT (or Com) port is a good start, and "USB2LPT" or USB2Seriell cable-adapters cost less than $10 (USD). In my opinion, an Ethernet2printer Adapter (printserver) or WLAN2printer adapter should be a modular option - not everybody needs this and with the first edition everybody could buy an external "JetDirect EX" (or what ever), but later editions should integrate an internal "JetDirect Card" (or what ever). I hate cables...

Why JetDirect: they are widely used and known to run. At ebay you can get an internal JetDirect-J2552 ethernet-printer-card for less than $25 (an external is ~ $50). Others are fine too, so not only JetDirect models should be certified - but nobody can know every model. And (AFAIK) they use an open (license free) interface specification.

Don't get too concerned about connectivity
Connectivity can be added later. The most important things are:
 * 1) making a mark on paper
 * 2) controlling the making of the marks
 * 3) moving the paper

For #2, what "language" will the printer implement? PCL or PS (postscript) are not the only ones available. Those are encumbered. But DVI (from Knuth via TEX) isn't.
