Other Printer Commands
The table below is a summary list of special commands that the laser printer emulation will obey if they
are imbedded in a user’s document.
Command
Function
¬E
Sends an ASCII ESC command to the printer
¬TY
Enables true 6 LPI printing
¬TN
Disable true 6 LPI printing
¬I
Ignores all host formatting commands
¬S
Stops ignoring host formatting commands
The ¬E command allows an
“Esc command to be sent to the printer to control the printing. Simple
"escape commands eliminate the need for putting in hex codes using Command Pass-Thru. These
commands allow use of some of the special features of the laser printer.
Check the printer
’s manual or any optional technical manual for a description of the feature and the
escape commands needed to access the feature. For example, ¬E(s3B would begin bold printing on an
HP LaserJet printer.
The I-O 5250 printer emulation module will slightly compress line spacing to fit 66 lines onto the page.
This may be undesirable (such as when using pre-printed forms that must align correctly). In these
cases, the ¬TY command prevents the printer from compressing the line spacing.
Use the ¬I and ¬S commands to remove unwanted host commands from a printer file. For example,
when printing with electronic forms software, the host recognizes these files as text files, which causes
the host to format the files with unwanted carriage returns and line feeds. Placing the ¬I at the end of a
line and ¬S at the front of the next line causes the I-O 5250 printer emulation module to remove the host
carriage return and line feed commands and send only the data to the printer.
I-
O’s laser printer emulation is compatible with many popular electronic forms software applications.
Matrix Printer Operation
IBM Matrix printer emulations
When printing to a dot-matrix printer, the I-O 5250 printer emulation module first converts 3812 SCS
commands to 4214 SCS commands. These 4214 SCS commands are then converted into one of the
following ASCII printer commands:
IBM PPDS (matrix)
IBM Proprinter
Epson ESC/P2
Epson DFX 8500/5000+ (no 15 CPI capabilities)
Epson FX/DFX
Epson LQ
