我用VFP9 SP1
如何用???指令列印中文 ? 我的程式如下 :-

----------------------------------開始
SET REPORTBEHAVIOR to 90
PRINTJOB
SET CONSOLE OFF
SET PRINTER TO lpt1
SET PRINTER ON
_PLENGTH = 66
_PADVANCE = 'LINEFEEDS'
_PEJECT = "NONE"
??? CHR(27)+"M"

? "不能顯示中文字"
?
?

SET PRINTER off
SET PRINTER TO
ENDPRINTJOB
----------------------------------結束

另一個問題是, 當碰到???指令時, 為何會跳了一頁才列印

去MSDN找了一下

??? Command

Sends output directly to the printer.

Syntax

??? cExpression

Arguments

cExpression

Specifies the characters that are sent to the printer.

Remarks

A group of three question marks bypasses the printer driver and sends the contents of cExpression directly to the printer. cExpression must contain valid printer codes.

Printer control codes allow you to reset the printer, change type styles and sizes, and enable or disable boldface printing. These codes can consist of any combination of printable or nonprintable characters that are specific to the printer you're using. You can direct control codes to the printer in several different ways:

Use combinations of CHR( ) and quoted strings concatenated with + to send ASCII characters directly to the printer.

Use quotation marks to send a string containing printer codes or ASCII characters.

Codes can be sent to the printer before printing begins and after printing ends with the _PSCODE and _PECODE system variables. For more information, see _PSCODE and _PECODE.
Printer control codes vary from printer to printer. The best source for information about printer control codes is the manual that came with your printer.

有些中文字內碼含有 '{' chr(123), ??? 會將 { 視為巨集, 因此導致無法顯示中文字, 因此在使用 ???
指令前, 必須先逐 byte 判斷, 如碰到 { ,則必換成 {{, 這樣才能正確的列印出中文
