Graphics Printing
The I-O 5250 printer emulation module will print the same Advanced Printer Functions (APF) and
Business Graphics Utility (BGU) graphics as the IBM 4214 printers using All Points Available (APA) bit
image graphics. This method is for printing continuous patterns such as bar codes and logos that come
from the AS/400 host. This is the method of graphic printing that IBM used before IPDS was developed.
The I-O 5250 printer emulation module implements the LAC command by taking the dot pattern
received from the
AS/400 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 printers.
Generic Mode
The Generic printer driver should be used when the other printer drivers of the I-O 5250 printer
emulation module are inappropriate. This could be the case with printers such as certain barcode label
printers or embossers, but also with printers from Okidata, Mannesmann-Tally, or others. Refer to the
printer’s user’s guide to find out if the printer operates with one of the I-O 5250 printer emulation
module’s print drivers.
In Generic mode, the I-O 5250 printer emulation module does not pass on the LPI and CPI commands
from the host. Rather, it allows you to match the printer specific CPI or LPI command with the CPI or
LPI command from the host (through Host Download commands 84 to 87).
For example, assume the printer protocol the printer requires is not available on the I-O 5250 printer
emulation module. To change the printer to 10 CPI, the printer’s user’s manual provides the
hexadecimal value of 1B 50. Use the Host Download command 86 to assign the value 1B 50 to the 10
CPI string (type &%Z86,1(1B 50)). From now on, when the I-O 5250 printer emulation module receives
a request for 10 CPI from the host, it will send the value 1B 50 to the printer and thereby set it to 10 CPI.
If nothing is assigned to the CPI or LPI string, the I-O 5250 printer emulation module will send nothing to
the printer, i.e. it will ignore the CPI or LPI command from the host.
The I-O 5250 printer emulation module stores commands for the following CPI and LPI values:
•
6 LPI
Host Download Command No. 84
•
8 LPI
Host Download Command No. 85
•
10 CPI
Host Download Command No. 86
•
15 CPI
Host Download Command No. 87
Command Pass-
Thru™
I-
O’s Command Pass-Thru feature allows access to all of the built-in features of the printer, even if
these features aren’t normally available through the host software. Command Pass-Thru lets you place
printer-specific command sequences into the data sent to the printer. The I-O 5250 printer emulation
module recognizes these special sequences and "passes the command through" to the printer.
The steps below describe how to use Command Pass-Thru.
1.
Find the command for the desired print feature in the printer’s user’s guide.
2. Convert the printer command to hexadecimal (ASCII).
3. Place &% (or the alternate CPT start delimiter), in the document at the point where the feature is
totake effect. This signals the start of the print feature.
