#Tandy Port Ext.
2 messages in this thread
I picked up a Tandy Parallel port extension kit today. I'm using with a
4000/40 and GVP IOExtender, set up as an IBM parallel port. It really
works. But the best part is this:
Time to print a fax normal cable 18 min
Time to print same fax with kit 4 min
That's right. For some reason The Tandy kit sped up throughtput by a
factor of 4.5. I am using ParPrefs to shift printing to the GVP board and
IBMPrt from AmigaUser libs.

Pin 14 on the kit is labeled as /autofeed. Does anyone think that sending
+5v from the regular Amiga port would hurt either?
Ash,
On many printers, having a voltage on pin 14 will make the printer
double space text. What 'autofeed' means is 'add a carriage feed after every
line feed'.
A line feed advances the tractor one space, a carriage return moves the
print head to the left margin. Typically, you need to send both a LF and a CR
when you reach the end of a line…so the paper advances one line and the print
head moves left.
In the MS-DOS world, an end-of-line is a CR/LF pair. On the Amiga,
it's only a LF. However, most Amiga printer drivers will add the CR, so if you
have your printer set to do that (autfeed on)…you will get double spacing on
the paper.
