Black Box PQ-8S Manual De Usuario

The PQ-8 implements the LAC

command by taking the dot pattern
received from the twinax host and
then printing that exact dot pattern
using the printer’s APA bit-image
graphics at high-density 240
dots/inch. This permits the printer
to print APF and BGU graphic
output using exactly the same
spacing as the IBM 4214/5224/5225
printers.

For normal or wide paper (14 7/8"
wide) printing, select Wrap through
Host/PC download command 26 or
the setup software. This allows
printing to extend the full width of
the wide paper. The printer wraps
printing beyond the margin to the
next line on narrow paper when it is
configured for narrow paper.

When using narrow paper (8 1/2"

wide), you can also select Truncate.
This ignores any printing beyond 8".
Documents must be formatted to fit
the narrow paper, since the text
beyond an 8" margin will truncate
(not print).

Epson 9-pin printers, IBM
Proprinters, and similar printers do
not have the capability to print at 15
CPI. When the host sends a 15 CPI
command, the PQ-8 is able to
produce an “artificial” 15 CPI on the
printer. This is accomplished by
printing 17.1 CPI and adjusting for
the spacing difference. In this
manner, 15 CPI fonts sent from the
host can fit on preprinted forms that
must align correctly.

When using the Epson 9-pin

printer driver, this is done
automatically. Since the Epson DFX
5000+ is able to print 15 CPI, make
sure to select the Epson DFX+ driver
when operating the DFX 5000+
printer.

When using the IBM Proprinter

driver, the user may manually select
whether 15 CPI host commands
should simply be printed as 17.1
CPI, or as 17.1 CPI with space
adjustments (see Host/PC download
command 28).  Printing the
“artificial” 15 CPI through the IBM
Proprinter driver significantly
reduces print speed.
